What gases does the gas Roots flowmeter measure?

Gas Roots flowmeter is an instrument for accurately measuring gas flow. It is based on the volumetric measurement principle and is used to accurately measure the total amount of gas flowing through a closed pipeline. The basic flowmeter consists of two parts: a rotary flow sensor and a flow integrator (secondary meter). 

Gas Roots flowmeter can measure gas 

. Gas Roots flowmeter is suitable for measuring non-corrosive gases such as natural gas, city gas, propane, nitrogen, and industrial inert gas.

Gas Roots flowmeter is mainly used in 

gas commercial settlement in industries such as catering and hotels, gas metering in transmission and distribution networks, gas pressure regulating station metering, gas metering for industrial and civil boilers, etc. It can also be used as a standard flowmeter.
