Gas Lobed Rotor (Roots) Flowmeter is a kind of gas monitoring and measuring instrument with high precision, high reliability and wide range. The intelligent Roots flowmeter is a new flowmeter that integrates flow, temperature, pressure sensors and intelligence on the basis of Roots flowmeter.
With the passage of gas, the pressure difference between the inlet and outlet of the gas meter acts on a pair of waist wheels connected together by a high-precision synchronous wheel, thereby driving the waist wheel to rotate, the gas filled with the metering room is quantitatively discharged, and then connected by a mechanical transmission and a calculator to achieve gas volume and data conversion.
It widely used in urban gas trade measurement, especially for organs, schools, enterprises and institutions, hotels, restaurants and other large gas users trade measurement. It can also be used for various industrial raw gas main metering, gas distribution station, main gas supply station and other occasions.
