Development of Adjustable Pressure Gas Flow Test Device

Inhalt:
With the more and more extensive application of gas flowmeter, the demand for the calibration of gas flowmeter is more and more vigorous. The adjustable pressure gas flow test device can not only meet the calibration requirements of small flow gas flowmeter, the operation is simple, intuitive and fast, but also can meet the measurement requirements of positive pressure or negative pressure flowmeter with working pressure greater than 2kPa. The establishment of adjustable pressure gas flow test device is of great significance for expanding the detection range of gas flowmeter, developing scientific research work and improving the performance of gas flowmeter.
