Abstract

The utility model relates to a kind of compressed air require proving installation, comprises intelligent flow calculator, large capacity meter and small flowmeter, and described large capacity meter and small flowmeter are arranged on pipeline respectively, and are connected with intelligent flow calculator respectively; When the flow on pipeline is greater than setting flow, described intelligent flow calculator reads the data of large capacity meter, when the flow on pipeline is less than setting flow, described intelligent flow calculator reads the data of small flowmeter, and described intelligent flow calculator shows the instantaneous delivery of reading and cumulative flow in real time.Compared with prior art, the utility model have measurement more accurately, reliability more advantages of higher.

Description

Compressed air require proving installation
Technical field
The utility model relates to a kind of flow testing device, especially relates to a kind of compressed air require proving installation.
Background technology
Compressed-air actuated flow measurement installs flowmeter to realize by the pipeline that flows through at pressurized air, generally on a road pipeline, a flowmeter is installed, cannot the accuracy of this flowmeter of Real-Time Monitoring, and all there is respective shortcoming in the air flowmeter used at present, as linearly bad when different flow of calorimetric flowmeter, vortex shedding flow meter cannot measure low discharge or Small flowrate measurement is inaccurate.
Utility model content
The purpose of this utility model be exactly provide a kind of to overcome defect that above-mentioned prior art exists and measure more accurately, compressed air require proving installation that reliability is higher.
The purpose of this utility model can be achieved through the following technical solutions: a kind of compressed air require proving installation, it is characterized in that, comprise intelligent flow calculator, large capacity meter and small flowmeter, described large capacity meter and small flowmeter are arranged on pipeline respectively, and are connected with intelligent flow calculator respectively;
When the flow on pipeline is greater than setting flow, described intelligent flow calculator reads the data of large capacity meter, when the flow on pipeline is less than setting flow, described intelligent flow calculator reads the data of small flowmeter, and described intelligent flow calculator shows the instantaneous delivery of reading and cumulative flow in real time.
Described large capacity meter is vortex shedding flow meter.
Described small flowmeter is thermal flowmeter.
Described large capacity meter is connected with intelligent flow calculator respectively by respective signal wire with small flowmeter.
Also comprise the supply module be connected with large capacity meter and small flowmeter respectively.
Compared with prior art, the utility model has the following advantages:
1) it is more accurate to measure, and the flowmeter that installation two is dissimilar on same pipeline, can contrast the measurement data of two flowmeters, if a certain flow meter data is inaccurate, and can Timeliness coverage.
2) reliability is higher, overcome the shortcoming that flowmeter exists separately, give full play to respective advantage, select vortex shedding flow meter to measure when large discharge, when low discharge, selected amount thermal flowmeter is measured, make compressed-air actuated flow measurement more accurate, more rationally can analyze efficiency objectively, the working condition etc. of compressibility.
Accompanying drawing explanation
Fig. 1 is structural representation of the present utility model;
Wherein 1, compressed air inlet pipe road, 2, large capacity meter, 3, small flowmeter, 4, pressurized air outlet pipe, the 5, first signal wire, 6, secondary signal line, 7, intelligent flow calculator.
Embodiment
Below in conjunction with the drawings and specific embodiments, the utility model is described in detail.
Embodiment
As shown in Figure 1, a kind of compressed air require proving installation, comprises intelligent flow calculator 7, large capacity meter 2 and small flowmeter 3, and described large capacity meter 2 and small flowmeter 3 are arranged on compressed air piping respectively, and are connected with intelligent flow calculator 7 respectively;
When the flow on pipeline is greater than setting flow, described intelligent flow calculator 7 reads the data of large capacity meter 2, when the flow on pipeline is less than setting flow, described intelligent flow calculator 7 reads the data of small flowmeter 3, the instantaneous delivery that the display in real time of described intelligent flow calculator 7 is read and cumulative flow.
Described large capacity meter 2 is vortex shedding flow meter.Described small flowmeter 3 is thermal flowmeter.Described large capacity meter 2 is connected with intelligent flow calculator respectively by respective signal wire with small flowmeter 3.
Vortex shedding flow meter measuring flow is more accurate, and precision is higher, but cannot measure low discharge.Thermal flowmeter is comparatively large at the larger time error of flow, but can Measurement accuracy low discharge.So two flowmeters are linked into intelligent flow calculator simultaneously, the data of read volume thermal flowmeter when low discharge, read the data of vortex shedding flow meter when large discharge, and can accomplish that the data read respectively are constantly accumulated in same data, add the accuracy that compressed air require is measured.
