Smart gas Roots (waist wheel) flow meter Intelligent gas waist wheel (Roots) flowmeter is a new generation flowmeter that integrates flow, temperature, and pressure detection functions, and can automatically compensate for temperature and pressure. Gas is a compressible fluid, and its volume value is closely related to temperature and pressure. In order to unify standards for both parties, it is necessary to convert the actual volume into a standard volume under reference conditions (101.325 kPa 20°C). In order to achieve this purpose, the smart gas waist wheel flowmeter can accurately correct the volume of gas; it is an ideal instrument for gas measurement in urban gas, petroleum, chemical, electric power, metallurgy and other industries. more
