Abstract
The utility model aims at providing an air -flow meter, including inner tube, outer tube and edge the float that the inner tube axle reciprocated, be equipped with the scale on the interior pipe wall, its characterized in that: still include infrared sensing module, grating, communication circuit and control terminal, the grating set up in on the scale of interior pipe wall, infrared sensing module install in on the outer pipe wall, with the grating is relative, communication circuit with infrared sensing module connects, communication circuit with control terminal connects. Whether blocked by the float through the grating that corresponds the scale and judge the flowmeter scale to it transmits the procedure for backstage management, the real time monitoring of being convenient for to pass through communication circuit with this information.
Description
Technical field
The utility model relates to a kind of air flowmeter, is specifically related to a kind of float-type air flowmeter of infrared real-time monitoring.
Background technology
The principle of suspended body flowmeter is: when fluid flows through glass tube from bottom to top, and between float is upper and lower, produce pressure reduction, float rises under this differential pressure effect.Buoyancy suffered by the power now risen, float and inviscid lift equal with the gravity of float time, float is in equilibrium position.Namely and there is certain proportionate relationship between the circulation area of flowmeter therefore, flow through fluid (gas or liquid) flow and the float lifting height of flowmeter, therefore the position height of float can be used as flow and measures.
Suspended body flowmeter, as flowing instruction directly perceived or the less demanding on-the-spot indicating instrument of measuring accuracy, is widely used in the public utilities such as process industry and wastewater treatment such as electric power, petrochemical industry, chemical industry, metallurgy, medicine.The water such as circulating cooling and culture tank or air subtract the glass tube suspended body flowmeter that the upper limit or lower limit flow alarm function can be selected in the places such as stream cutout warning.But float-type air flowmeter on the market all needs artificial observation, report, easily there is error and then damage instrument in this, also consume a large amount of manpowers simultaneously.
Summary of the invention
The purpose of this utility model is to provide a kind of air flowmeter, can realize infrared on-line monitoring, carries out Realtime Alerts to gas velocity.
The utility model realizes by the following technical solutions: a kind of air flowmeter, the float comprising interior pipe, outer tube and move up and down along described interior tubular axis, described inner tubal wall is provided with scale, it is characterized in that: also comprise infrared sensing module, grating, telecommunication circuit and control terminal; Described grating is arranged on the scale of described inner tubal wall; Described infrared sensing module is installed on described outer tube wall, relative with described grating; Described telecommunication circuit and described infrared sensing model calling; Described telecommunication circuit is connected with described control terminal.
In the utility model one embodiment, described telecommunication circuit is a radio communication circuit.
In the utility model one embodiment, also comprise an alarm, described alarm is connected with described control terminal.
In the utility model one embodiment, also comprise a display screen and display drive circuit, described display drive circuit is connected with described control terminal; Described display drive circuit is connected with described display screen.
Preferably, described interior pipe, outer tube are transparent glass tube.
Compared with prior art, whether the utility model is judged flowmeter scale by float blocking-up by the grating of corresponding scale, and this information is transferred to Background control terminal by telecommunication circuit, be convenient to real-time monitoring, when arriving scale described in flowmeter, reported to the police by alarm, can also be shown by a display module flow meter scale, convenient operation personnel carry out real-time monitored.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described further.
The utility model provides a kind of air flowmeter, the float 3 comprising interior pipe 2, outer tube 1 and move up and down along described interior tubular axis, and described inner tubal wall is provided with scale, infrared sensing module 4, grating 5, telecommunication circuit 6 and control terminal; Described grating 5 is arranged on the scale of described inner tubal wall; Described infrared sensing module 4 is installed on described outer tube wall, relative with described grating; Described telecommunication circuit 6 and described infrared sensing model calling; Described telecommunication circuit 6 is connected with described control terminal.If float 3 rises to the position that grating pair is answered, block the infrared ray that infrared sensing module is launched, infrared sensing module produces a signal, and this signal is sent to control terminal by telecommunication circuit, can be learnt the scale of flowmeter by control terminal.Fig. 1 is the structural representation of the utility model one embodiment.In FIG, grating and infrared sensing module installation, in other embodiments also can by grating and infrared sensing module installation outside tube walls inside tube wall.
In the utility model one embodiment, described telecommunication circuit is a radio communication circuit.Specifically look user's request, bluetooth communication circuit, WiFi communication circuit or ZigBee communication circuit can be selected.
In the utility model one embodiment, also comprise an alarm, described alarm is connected with described control terminal.When the scale that the scale arrival grating pair of flowmeter is answered, control terminal controls alarm action, plays warning function to operating personnel.
In the utility model one embodiment, also comprise a display screen and display drive circuit, described display drive circuit is connected with described control terminal; Described display drive circuit is connected with described display screen.Display screen flow meter scale shows, and convenient operation personnel carry out real-time monitored.
Preferably, described interior pipe, outer tube are transparent glass tube.The infrared ray that infrared sensing module is launched has very strong penetration power, and transparent glass tube is less even negligible to ultrared influence power.But metal pair infrared ray has certain absorbability, therefore metal tube should not be selected.Contrary float should be selected and can block ultrared material, general float of the prior art and infrared ray capable of blocking.
In sum; the above-listed preferred embodiment that the utility model provides; the purpose of this utility model, technical scheme and advantage are further described; be understood that; the foregoing is only preferred embodiment of the present utility model, not in order to limit the utility model, all within spirit of the present utility model and principle; any amendment of doing, equivalent replacement, improvement etc., all should be included within protection domain of the present utility model.
