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

a. The length of the straight pipe section of the pipe to be tested at the installation of the flowmeter shall meet: upstream 20D distance, downstream 10D distance (D is the inner diameter of the pipe). By using our rectifying flowmeter (pipe diameter ≤ DN100), the length requirements of the front and rear straight pipe sections can be greatly reduced.
b. The flow regulating valve should be installed as least 10D far from downstream of the flowmeter . If it must be installed at the front end, it should be far away from the measuring point.
