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

It uses a more beautiful design, with double circlip, ten-layer V-type PTFE gasket, and flange with concave and convex surface, so that the meter will not leak under high pressure, which is more convenient for use, disassembly and maintenance.
LKQ-A2F3 anti-corrosion type
He anti-corrosion type thermal gas mass flowmeter has all the features of the conventional thermal mass flowmeter and the sheath of the sensor is made of special metal material tantalum with good acid corrosion resistance, and in the concentration of 28~29% hydrochloric acid ( at this concentration, hydrochloric acid is the most corrosive to metals.) the wall thickness will be corroded by 4u every year. If the wall thickness of the sheath is to be completely corroded, it takes more than ten years,moreover, the corrosive properties of chlorine, phosgene and other gases actually used are not as corrosive as the concentration of 28, 29% hydrochloric acid solution, and the PBF probe and the pipe to be tested are reliably sealed.

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.
