Zld-2 orifice multistage flowmete

Zld-2 orifice multi-stage flowmeter is processed according to the principle of orifice flowmeter
It is used to test the gas emission flow of borehole, that is, the initial velocity Q index of borehole gas emission
This index is used to predict the risk of coal and gas in local excavation
The orifice multi-stage flowmeter is fully configured and the test method is simple and easy
It is one of the gas parameter test equipment commonly used in coal mines and appraisal institutions
Zld-2 orifice multi-stage flowmeter is made of acrylic material, which is not fragile and corrosion-resistant, and the scale is concave carved, which is not easy to be damaged; The test elements such as multi-level orifice plate of the equipment meet the standards, the supporting facilities are complete, and it is convenient to carry down the well; Technical parameters of zld-2 orifice multistage flowmeter , Range: 0 ~ 1
