Abstract
1,051,209. Rotary meters. ROLLS-ROYCE Ltd. July 29, 1965. No. 32567/65. Heading F1F. A rotary meter for measuring the rate of fluid flow through a conduct 3, Fig. 3, comprising a rotor hub 5 formed with a plurality of blades (not shown) rotatable by the fluid is carried by a shaft 6 which through a magnetic coupling 13, 14 rotates a shaft 12 carrying a disc 16 with a plurality of holes 17, therethrough. The disc 16 is interposed between a photo-electric cell 27 and a mirror 21 reflecting light from light sources 23 located in "in-line" relationship with the bores in tubular struts 4 concentrically supporting a body member 9 in which the shaft 12 is bearingly mounted. The body member 9 is sealed against inflow of fluid by a non-magnetic non-conducting inflexible diaphragm 15 interposed between the magnetic coupling parts. As the rotor hub 5 together with its blades and the shafts 6 and 12 rotate the light from the sources 23 reflected by the mirror 21 is interrupted by the metal between the holes 17, so that pulses of light falling upon the photo-electric cell 27 are transformed into corresponding electric pulses which are sent to a calibrated counter to determine the flow rate of the fluid. The mirror may be omitted and the blades made of light reflecting material to reflect light from the light source on to the photo-electric cell. The mirror 21 and the member 19 on which it is mounted may rotate with the shaft 12 in which case the disc 16 can be dispensed with.
