LGH-type High Pressure Gas Flow Standard Testrig

Using clean air as medium, the air is driven by the blower and flow circularly in the closed loop 

The air inside the loop reaches the setting pressure value through the compressor and pressure regulator valve group, meanwhile, the temperature inside the loop reaches the set value through heat exchanger and cooling system.

Then by comparing the volume flow through MUT and Master Meter at the same period, to obtain the error of indication and repeatability of MUT.

Functionalities 

● The device can be used for detection and calibration of various gas flowmeter,

● The device can test the performance of gas flowmeter under positive pressure condition to provide reference data for research and development.

Key Technologies
