Aister manufacturer teach you how to choose the thermal gas mass flow meter?
2023-11-24
There are many types of thermal gas mass flow meters on the market now, and different thermal gas mass flow meters are used in different industries. Aister specializing in mass flow meter manufacturers, many people may not know how to choose this, then today I will share with you the selection of thermal gas mass flow meter.
1. thermal mass flow meter is divided into insertion type and pipe section type two, different styles apply to different places. Insertion type thermal gas mass flow meter used in large caliber, pipe section type can be applied to high temperature occasions corrosive environment.
2. the real mass flow meter, the gas quality measurement without temperature and pressure compensation, measurement is convenient and accurate. Can get the gas mass flow or standard volume flow. And we measure the medium is not to contain water, can not have impurities. All kinds of gases can be measured mass flow, except acetylene gas.
3. according to the characteristics of the measured medium to choose a reasonable measurement method, according to the measured medium and measurement accuracy requirements, respectively, the insertion type flowmeter, speed element with differential pressure meter, ultrasonic flowmeter, or the use of marking method, analog method, and other incapable of loss of flow measurement.
4. thermal gas mass flow meter selection is in accordance with the production requirements, should start from the actual situation of the instrumentation product supply, comprehensive consideration to determine the flow sampling device and gas flow meter form specifications!
5. pay attention to the gas flowmeter shock requirements, to correctly select the specifications of the gas flowmeter, gas flowmeter pressure should be slightly greater than the working pressure of the measured medium, generally go 1.25 times. Ensure that the gas flow meter will not leak!
