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.
Intelligent Gas Roots flowmeter is the ideal instrument for measuring natural gas, city gas, gas, nitrogen, industrial inert gas and other non-corrosive gases.
