Abstract
A meter mounting assembly has a meter support plate (10) on which is mounted a water meter and a valve assembly controlling the flow of water through passages in the plate (10) to the meter. Inlet and outlet pipes (15, 17) are provided connected to the meter support plate (10) and the whole metering assembly may be mounted in a lined cavity. As shown, the support plate (10) comprises upper and lower parts (11), (12) and is connected to a base (13) with recesses (19, 20) on its surface which engage passages (21, 22) extending from the motor support plate (10). In another arrangement, the inlet and outlet pipes pass through the base and engage the support plate directly. The inlet and outlet of the meter may be coaxial and the motor support plate may be designed to connect to such a meter. A further alternative is that the base be emitted and the meter support plate amended directly to the liner of the cavity. <IMAGE>
Description
A METER MOUNTING ASSEMBLY
The present invention relates to a meter mounting assembly for mounting a meter such as a water meter. The present invention is concerned with several different aspects of such an assembly.
In EP-A-0317061 and my UK Patent Application No.
8926649.8 I discussed various meter mounting assemblies.
The present invention seeks to modify and adapt such assemblies.
The first aspect of the present invention proposes that the assembly has a meter support plate and a base secured together with telescoping engagement of flow-ways extending from the meter support plate into recesses in the base. It may be recalled that in EP-A-0317061 there was telescoping engagement of the flow-ways of the base.
Therefore, the first aspect may provide a meter mounting assembly, comprising;
a base having a pair of recesses therein, the base of each recesses communicating with a corresponding flow-way;
a meter support plate having a pair of flow-ways extending therefrom, the flow-ways respectively sealed in telescopic engagement with the interiors of the recesses in the base, thereby to interconnect the flow-ways of the meter support plate and the base; and
securing means for securing together the meter support plate and the base.
In EP-A-0317061 and my UK Patent Application No.
8926649.8 the meter assembly was secured to the support plate by a locking ring. The locking ring slid over the outer casing of the meter assembly and rested on an abutment means on that casing. When the locking ring was secured to the meter support plate, the outer casing was held in place due to the abutting of the abutment means and the locking ring. However, there was then the risk that the locking ring could get lost when it was slid off the outer casing and so the second aspect of the present invention proposes that there is a second abutment means on the outer casing which, together with the first abutment means, retains the locking ring.
Therefore the second aspect of the present invention may provide a meter mounting assembly comprises
a meter support plate;
a meter assembly housing an outer casing; and
a locking ring surrounding the meter assembly and releasably securing the meter assembly to the meter support plate;
wherein the meter assembly has a pair of spaced apart abutment means thereon, thereby permitting movement of said locking ring on the meter assembly for engaging and disengaging the meter support plate but preventing removal of the locking ring from the meter assembly.
Preferably the retaining ring retains a meter display part on the outer casing.
The third aspect is concerned with the connection of the meter support plate to the pipes which, when the meter support plate supports a water meter, are the water inlet and outlet pipes. In EP-A-0317061 the pipes were connected to a base, which engaged the meter support plate. However, the third aspect of the present invention proposes that the pipes pass through bores in the base and make direct engagement with the meter support plate.
Therefore, the third aspect may provide a meter mounting assembly comprising;
a base plate having a pair of bores therein;
a pair of pipes extending through said bores;
a meter support plate having a pair of flow-ways therein and means for securing the meter support plate to the pipes such that the pipes communicate respectively with the flow-ways in the meter support plate; wherein the pipes are sealed to the bores.
In EP-A-0317061, the water from the inlet between an outer casing and a meter casing before it entered the meter. However, some meters have their inlet and outlet flow-ways arranged coaxially, and therefore, to adapt to this type of meter, the fourth aspect of the present invention proposes that there is a sealing ring between the outer casing and on outer wall of the coaxially outer flowway to direct the water or other fluid to be metered into that outer flow-way.
Thus, in the fourth aspect, the present invention may provide a meter mounting assembly comprising:
a meter support plate having a first flow-way, and a second flow-way and means for receiving a meter assembly; and
a meter assembly received in the receiving means, the meter assembly comprising an outer casing secured to the meter support plate, a meter within the outer casing, the meter having a first flow-way axially aligned with the first flow-way in the meter support plate and a second flow-way coaxial and outside the first flow-way of the meter, and a sealing ring extending between the outer casing and an outer wall of the second flow-way of the meter, such that the second flow-way of the meter and the second flow-way of the meter support plate are in fluid communication.
Finally, in EP-A-0317061 and my UK Patent Application
No. 8926649.8, the meter support plate was always secured to a base. In a fifth aspect of the present invention it is proposed that the base be omitted. The meter support plate may then be attached directly to the inner wall of the liner of the cavity into which the meter assembly is to be located.
Therefore, in a fourth aspect of the present invention there is provided a meter mounting assembly comprising:
a liner for mounting in a cavity;
a meter support plate secured to the interior of the liner having a first and second flow-ways for fluid communication therethrough;
a pair of pipes extending into the liner and respectively engaging the flow-ways of the meter support plate;
a valve assembly engaging the first flow-way of the meter support plate for releasably sealing that the first flow-way; and
a meter assembly mounted on the meter support plate and secured thereto such that internal flow-ways of the meter assembly are in fluid communication with the first and second flow-ways of the meter support plate;
wherein the engagement of the pipes and the flow-ways is such that the pipes engage a part of the meter support plate which is integral with the part of the meter support plate secured to the liner and with the flow-way engaged by the valve.

Fig. 14 shows a twelfth embodiment of the present invention.
A first group of embodiments of the present invention is concerned with the structure of the meeting assembly for supporting a water meter assembly and, preferably, a valve assembly. In the three embodiments of this first group, the meeting assembly comprises a base and a meter support plate.
In Fig. 1, the meter support plate 10 comprises an upper part 11 and a lower part 12, which are secured to a base plate 13 by means of bolts 14 which extend through the two parts of the meter support plate 11, 12 into the base plate 13 to clamp those parts together. An inlet pipe 15 enters the base plate 13 and communicates with a flow-way 16 in that base plate 13. In a similar way, an outlet pipe 17 extends from the base plate 13, which outlet pipe 17 is in communication with a flow-way 18. The flow-ways 16 and 18 open into recesses 19, 20 respectively in the upper surface of the base plate 13, which recesses 19, 20 are aligned with respective spigots 21, 22 projecting downwardly from the lower part 12 of the meter support plate 10. The spigots 21, 22 are sealed to the recesses 19, 20 by 0-ring seals 23 24.Flow-ways 25, 26 extend through the lower part 12 of the meter support plate 10, passing through the spigots 21, 22 and so communicate with the flow-ways 16, 18 in the base plate 13.
It can thus be seen that the telescoping interconnection of the spigots 21, 22 and the recesses 19, 20 permit simple and straight forward mounting of the meter support plate 10 on the base plate 13. A fluid communication path is established from the inlet and outlet pipe 15, 17 through the lower part 12 of the meter support plate 10, sealing being achieved by the 0-rings 23, 24.
The upper part 11 of the meter support plate 10 has a first part 27 for mounting a valve assembly thereon, and a second part 28 for receiving a meter assembly. As can be seen, there is a recess 29 in the lower surface of the upper part 11 of the meter support plate 10, communicating with the flow-way 25, and by sealing the outlet of the flow-way 25 e.g. by valve part 30, flow may be stopped. In a similar way, if the flow-way 25 is opened, fluid can flow into the recess 29 and from thence via passage 31 into the meter. A one- way valve 32 may be provided in the upper part 11 of the meter support plate 10 aligned with the part 28 which reseeds the meter, and the upper and lower parts 11, 12 of the meter support plate 10 maybe secured together by a suitable fastening such as bolt 33.
Thus, suppose that the assembly shown in Fig. 1, with attached meter and valve assembly is mounted in e.g a cavity in the ground, which cavity may be lined as I described in my UK Patent specification GB-A-2210465.
Then, if the meter or valve assembly need to be replaced, it is a straight forward matter to unscrew the bolts 14 and thereby release the meter support plate 10 from the base plate . The base plate 13 may be fixed in the cavity, e.g.
by interconnection of lugs 34 with the liner of that cavity, but the meter support plate 10 is then removable from the cavity without having to gain access to the base of the base plate 13. Furthermore, the telescoping arrangement of spigots, 21, 22 and recesses 19, 20 insure that the flow-ways 25, 26 through the meter support plate 10 are sealed to the flow-ways 16, 18 through the base plate 13 without a complicated arrangement.
Fig. 2 shows a second embodiment of the present invention, which is generally similar to that of Fig. 1, and the same reference numerals are used to indicate corresponding parts. In the second embodiment, shown in
Fig. 2, the spigots 21, 22 are lengthened so that the lower part 12 of the meter support plate 10 is held clear of the base plate 13, but otherwise the interconnection of the meter support plate 10 and the base plate 13 is the same.
The bolts 14 are longer, in order to accommodate the extra length of the spigots 21, 22 but again a suitable sealing interconnection of the flow-ways 16, 18 in the base plate 13 and the flow-ways 25, 26 in the lower part 12 of the meter support plate 10 is achieved by the telescoping interconnection of the spigots 21, 22 and the recesses 19, 20, sealed by 0-rings 23, 24.
A further modification, shown in Fig. 2, is that, if the upper part 11 of the meter support plate 10 is made of plastics material, a metal ring 40 may be provided in the upper part 11 of the meter support plate 10 adjacent the top section 41 of that part 28 of the upper part 11 of the meter support plate 10 which is to be connected to the meter assembly. This gives greater strength to the fastening of the meter assembly to the upper part 11 of the meter support plate 10.
The third embodiment of the present invention, shown in Fig. 3, is a modification of the second embodiment shown in Fig. 2, and again the same reference numerals are used to indicate corresponding parts. However, in the third embodiment shown in Fig. 3, there is no direct fixing together of the meter support plate 10 and the base plate 13. Instead, the base plate 13 is fixed to the lining 50 of the cavity in which the meeting assembly is to be mounted, and that lining 50 has lugs 51 there on. The meter support plate 10 is mounted on those lugs 51 and secured thereto by the bolts 14.Thus, the fixing together of the lower part 12 of the meter support plate 10 and the base plate 13 is indirect, via lining 50, but again the telescoping interconnection of spigots 21, 22 and recesses 19, 20 ensure that a suitable joining of the flow-ways 16, 18, in the base plate 13 and the flow-ways 25, 26 in the lower part 12 of the meter' support plate 10 is achieved.
In the first three embodiments, discussed above, the inlet and outlet pipes 15, 17 could be arranged to extend from the sides, rather than the bottom, of the base plate 13, by suitably shaping the flow-ways 16, 18. The liner of the cavity into which the assembly is to be mounted could be a plastics, clay or concrete chamber.
The second group of embodiments includes the fourth embodiment of the present invention which will now be described with reference to Fig. 4. This embodiment is primarily envisaged as a modification of the assembly for supporting a meter discussed in my European Patent
Application No. 88308999.7, but the principle is applicable to other arrangements.
In Fig. 4, the metering assembly for supporting a meter has a base plate 60 having upwardly extending spigots 61, 62 which engage telescopically with downwardly engaging the flow-ways 63, 64 of a meter support plate 65. The meter support plate 65 may be fixed to the base 60 via pillars in a way that was described in my European Patent
Application No. 88308999.7. The meter support 65 contains a valve assembly 66 and a meter assembly generally indicated at 67. It is the structure of this meter assembly with which this embodiment is primarily concerned.
As shown in Fig. 4 the meter assembly 67 comprises an outer casing 68, and four meter components being a meter display components 69, a ring component 70 with apertures therein to allow water to passs therethrough, a turbine or piston component 71 and a magnetic drive 72 driven by the turbine or piston component 71, which magnetic drive component 72 drives the meter display component 69. Those components are supported by a meter cradle 73, which meter casing 73 is clamped to the interior of the outer casing 68 by a locking ring 74. The outer casing 68 is received in a recess in the meter support plate 65 and is secured there to by a locking ring 75, which locking ring 75 bears on a shoulder 76 at the lower end of the casing 68, and which engages a corresponding engagement mark 77 of eg. metal in a part of the meter support plate 65.
As this described, the fourth embodiment of the present invention is generally similar to the assembly described in my European Patent Application No. 88308999.7.
However, in that application the meter display component was contained wholly within the outer casing. In the present embodiment, however, as shown in Fig. 4, it can be seen that the meter display components 69 is mounted above a flange 78 in the outer casing 68, which flange 78 has an opening 79 therein to permit satisfactory magnetic linking of the drive component 72 and the meter display component 69. The meter display component 69 is then held on to the outer casing 68 by a retaining ring 80, which retaining ring 80 is secured to the outer casing 68 by suitable means such as adhesive or threading. The use of such a retaining ring has the advantage that the same casing 68 may be individually adapted to different configurations of meter display component 68, by suitable design of the retaining ring 80, but there is a further advantage.In the original arrangement, described in my European Patent Application
No. 88308999.7, it was possible for the locking ring 75 to be unscrewed from the meter support plate 66 and completely removed from the outer casing. There was then the risk that the locking ring 75 could get lost. However, it can be seen from Fig. 4 that the provision of the retaining ring 80 prevents the locking ring 75 from being removed from the outer casing 68, so that a more practical arrangement is achieved.
There is a further advantage, since the actual length of the casing 68 in the embodiment to Fig. 4 is shortened relative to an arrangement where that outer casing 68 has to extend at least partially around the meter display component 69. This reduction in the length of the outer casing 68 increases its strength, permitting it to withstand the greater pressures. It can be appreciated that, water from the inlet pipe 81 passing via the valve assembly 66, and the flow-ways 82, 83, enters the space 84 between the outer casing 68 and the meter cradle 73. As the casing 68 must withstand that pressure. As shown in
Fig. 4, a filter 84a may be provided between the flow-way 83 and the space 84 . After passing through the space 84, water flows through the ring component 70 and through the turbine component 71 to a flow way 86, and hence via a nonreturn valve 87 to the outlet pipe 88.The ring component 70 is sealed to the outer casing 68 by an 0-ring 85.
The next group of embodiments are (the third group) concerned with further modifications of the interconnection of a meter support plate and a base plate, which may be used with the arrangements described in my European Patent
Application No. 88308999.7 or in my UK Patent Application
No. 8926649.8. In those applications, and indeed in the embodiments discussed earlier in this application, the inlet and outlet pipes terminate within the base plate, and communicate with flow-ways in the base plate, which flowways again communicate with corresponding flow-ways in the meter support plate.
Fig. 5 shows an embodiment in which the inlet and outlet pipes pass entirely through the base plate.
Referring to that figure, a meter support plate 90 contains a valve generally indicated at 91 and a part indicated at 92 for receiving a meter assembly. A flow way 93 is defined through the meter support plate 90, and there is an outlet 94 containing a one way valve 95. The assembly of this embodiment also has a base plate 95 which, as shown in
Fig. 5, may be mounted within a concrete liner 96 of an underground cavity, and may support a chamber 97 with a removable lid 98 extending over the rest of the metering assembly. The base plate 95 has bores 96, 97 therein, through which pass the inlet pipe 98 and the outlet pipe 99 respectively. The inlet pipe 98 extends to an opening 100 in the meter support plate 90 below the valve assembly 91, and the inlet pipe 98 is secured to that opening 100 by a locking ring 101 or other suitable means.In a similar way, the outlet pipe 99 extends to another opening 102 in the meter support plate 90 below the part 92 of that plate 90 which is to receive the meter assembly, and again is secured thereto by a locking ring 103 or other suitable means. It can thus be seen that the inlet and outlet pipes 98, 99 pass completely through the base plate 95. Grommets 104, 105 maybe provided in the bores 96, 97 to seal the inlet and outlet pipes 98, 99 to the base plate 95.
The sixth embodiment, shown in Fig. 6 is generally similar to the fifth embodiment, shown in Fig. 5, and the same reference numerals are used for corresponding parts.
In the embodiment shown in Fig. 6, however, the base plate 95 has a flange 110 thereon, which flange 110 is received between mating surfaces 111, 112 of part of the liner 96 of the cavity in which the meeting assembly is to be mounted.
With this difference, the embodiment in Fig. 6 is the same as the fifth embodiment.
The fourth group of embodiments are concerned with the changes necessary in the metering assembly to permit use of a meter which operates to measure fluid flowing through the meter in the opposite direction to the direction of flow in the embodiment of Fig. 4, or indeed the arrangements described in our European Patent Application No.
88308999.7.
Fig. 7 shows a shows a seventh embodiment of the present invention, which is a modification of the fourth embodiment shown in Fig. 4, but using a reverse-flow meter.
Therefore, the same reference numerals are used to indicate corresponding parts, and those parts which perform the same operation as the fourth embodiment will not be described in detail. As in the fourth embodiment, the components of the meter are contained within an outer casing 68 which is secured to the meter support plate 65 by a locking ring 75.
However, the interconnection of the meter assembly to the various flow ways in the meter support plate 65 is different in the seventh embodiment.
Fluid such as water flows from the main and enters via inlet pipe 81, passing through base plate 60 and via flow ways 82, 83 to the recess in the meter support plate 65 which receives the outer casing 68. That flow may be controlled by valve assembly 66, in a manner generally similar to the embodiment in Fig. 4 and European Patent
Application No. 88308999.7. A filter 84 is provided immediately within the outer casing 68, to filter the fluid passing through the flow way 83. A blank locking ring 120 then extends from the inner wall of the casing 68 to an outer surface of the meter cradle 121, and is sealed thereto by seals 122. Immediately inside the part of the meter cradle 121 adjacent the ring 120 is a flow way 123, and the blank locking ring 120 causes fluid passing through the filter 84 to be guided into that flow way 123 and hence into the meter.The fluid then enters the interior 124 of the meter cradle 121 and passes through the piston component 71 of the meter, which piston component 71 drives a drive component 125 which activates the display component 126 of this design of meter. Water having passed through the piston component 71 is prevented from escaping from the top of the outer casing 68 by a pressure plate 127 sealed by seals 128 to the interior of the outer casing 68. The fluid then passes between the meter cradle 121 and the outer casing 68, through space 129, and then to space 130 which communicates with an outlet flow-way 131 of the meter via an aperture 132. The outlet 131 is sealed to a connecting ring 133 mounted on the meter support plate 65 so as to be in communication with the outlet flow-way 134 which communicates with the outlet pipe 88. Again, a nonreturn valve 87 may be mounted in that flow way.
The pressure plate 127 should be designed to resist the pressure inside the outer casing 68 and the pressure plate 127 is held in place by the upward pressure from the components of the meter assembly, which apply pressure to the seal 128. To improve this effect, a key-way 135 may be provided on the lower surface of the blank locking ring 120, which applies an upward thrust to that locking ring 120 and hence to a shoulder 136 on the meter cradle 121.
Fig. 8 shows another embodiment of the present invention, which is a variation on the seventh embodiment shown in Fig. 7, but with a slightly different meter arrangement. Again, the same reference numerals are used where appropriate.
In this eighth embodiment, the meter display component 126 is mounted on the outer casing 68 via a retaining ring 140, which retaining ring corresponds to the retaining ring 80 in Fig. 4. The other change from the seventh embodiment concerns the details of the interconnection of the meter assembly and the meter support plate 65. As shown in Fig.
8, the meter cradle 121 terminates at its lower end in a flange 141, which engages the side of the outer casing 68.
A locking ring 142 then clamps the meter cradle 121 inside the outer casing 68. It can be seen that the flow-way 123 is immediately inside the flange 141, so that there is a direct flow path to the space 124 via the flow-way 123 from the flow-way 83. Again, fluid which has passed through the turbine or piston component 71 and out into the space 129 between the meter cradle 121 and the outer casing 68 passes from space 130 through opening 132 into an outlet flow-way 131 in a suitably shaped component 133 which interconnects the meter casing and the meter support plate 65. Again, suitable seals are provided.
The fifth group of embodiments represents a departure from the earlier embodiments, and indeed from my European
Patent Application No. 88308999.7 and GB-A-2210465, in that there is no base plate. Instead, inlet and outlet pipes are connected directly to the meter support plate, and that meter support plate is mounted on the liner in the cavity in the ground in which the meter and valve are to be located.
Fig. 9 shows a ninth embodiment to the present invention. In fig. 9, a base plate 200 supports a meter assembly 201 and a valve assembly 202. The mounting of the meter assembly 201 and valve assembly 202 on the meter support plate 200, and the internal structure of the meter assembly 201 and the valve assembly 202 is generally similar to arrangement described in my European Patent
Application No. 88308999.7. It is thus also similar to the fourth embodiment to the present invention, described with reference to fig. 4, although in the embodiment shown in fig. 9, the display element 203 of the meter assembly 201 is held in place by part of the casing 204, rather than by a separate retaining ring 80. Furthermore, the engagement surface 77 in Fig. 4 is integral with the meter support plate 200 in Fig. 9.Therefore, because of the general similarity between Figs. 4 and 9, the structure and mounting of the meter assembly 201 and valve assembly 202 will not be described in detail.
In the embodiment to Fig. 9, however, the downwardly extending flow-ways 205, 206 of the meter support plate 200 do not telescopically engage a base plate, but instead are threaded at their ends so that they can be connected to inlet and outlet pipes 207, 208. This direct connection of inlet and outlet pipes 207, 208 to flow-ways 205, 206 of the meter support plate 200 eliminates the need for a base plate.
In previous embodiments, the assembly was secured to the liner 209 of the cavity in which the assembly is located by connection of the base and that liner. In the embodiment shown in Fig. 9, this is not possible due to the absence of the base plate and therefore the meter support plate 200 has a flange 210 which is connected to the liner 209 via eg. a screw 211.
With such an arrangement, it remains possible to remove the meter assembly 201 from the cavity without significant effort. By unscrewing the locking ring 212 (corresponding to locking ring 75 in Fig. 4) the casing 204 of the meter assembly 201 is released from the meter support plate 200, and all other interconnections of the meter assembly 201 and meter support plate 200 are sliding.
Therefore, the meter assembly 201 can be removed from the meter support plate 200.
Of course, the meter support plate 200 may be attached to the liner 209 by means other than screw 211, eg. by welding. Welding can also be used, if desired, to connect together the inlet and outlet pipes 207, 208 and the flowways 205, 206.
The tenth embodiment of the present invention, shown in Fig. 10, represents a variation on the embodiment of
Fig. 9, in that instead of the use of screws 211, the meter support plate 200 has a flange 220 which extends between adjacent blocks 221, 222 of the liner 223. Again, however, secure mounting of the meter support plate 200 within the liner 223 is achieved. In the embodiment shown in Fig. 10, the connection of inlet and outlet pipes 207, 208 to downwardly extending flow-ways 205, 206 this means that the base plate is omitted.
The embodiment of Fig. 10 also adapts the base plate 200 to a different meter assembly 224. The meter assembly 224 is self-contained, and so does not need a housing.
Instead, a support ring 225 is positioned on the meter support plate 200 and held in place by a locking ring 226 (which thus preforms the same function as locking ring 212 in Fig. 9).
Fig. 10 also illustrates a further development of the present invention, which is applicable not only to this embodiment but also to the other embodiments described in this application. It can be recalled from, eg. the embodiment to Fig. 4 that the locking ring 75 engages an insert 77 of eg. metal in the meter support plate 65. In the embodiment shown in Fig. 10 there is a similar metal insert 227. There is a risk, however, that the metal insert 77, 227, could pull out or lift slightly when the locking ring 75, 226 is tightened. The tightening of the locking ring 75, 226, combined with the constant upward thrust created by the pressure in flow-way 83, 228 could result in a creeping action. In the embodiment to Fig.
10, this could allow the bottom shoulder 229 of the metal insert 227 to separate from the shoulder 230 of the meter support plate 200, and at the same time the bottom edge 231 of the support ring 225 could lift off the seal 232 thereby slackening the seal and allowing water to pass.
Therefore, as shown in Fig. 11, pins 240 extend over the insert 226 thereby holding the insert 226 in place.
The pins 240 can either be moulded directly into the meter support plate 200 adjacent the inset 226, or can be inserted in a bore 241 as shown in Fig. 12. The pin 240 is then held in place by a bolt 242. Fig. 12 also shows shoulders 243 which assist in the retaining action of the bolt 242 or indeed, if sufficiently strong, may replace it.
It can be seen from Fig. 12 that the top of the pin 240 overlaps the top of the insert 226, thereby retaining the insert 226.
The next embodiment of the invention, shown in Fig.
13, is generally similar to the embodiment to Fig. 9, in that the meter support plate 200 is connected to the liner 209 via a flange 210 which is secured to the liner 209 by a pin 211. In the embodiment shown in Fig. 13, however, the liner 209 is relatively short, so that the inlet and outlet pipes 207, 208 extend directly into the ground.
Fig. 13 also shows that the liner 209 may have a transparent lid 250 with a magnifying glass 251 moulded therein. To make the lid tamperproof there is one or more ties 252 which sealed together the lid 250 and the liner 209. In the embodiment to Fig. 13 there is also the opportunity of remote monitoring of the meter, as the display component 203 of the meter assembly 201 is connected to a cable 253 which passes through a duct 254.
The cable 253 may be arranged for telemetry and may be connected to a suitable recording instrument remote from the meter assembly.
Fig. 14 shows another variation on this embodiment in which the liner 209 has a lower plate 260 through which pass the inlet and outlet pipes 207, 208. Seals 261, 262 may be provided to seal the inlet and outlet pipes 207, 208 to this plate 206. These seals 261, 262 prevent the ingress of water and the plate 260 is secured to the rest of the liner 209 by screws 263. This arrangement is particularly, but not exclusively, adapted to an arrangement in which the liner 209, and possibly the base 206 are of metal e g. iron.
