Intelligent gas roots flowmeter is a new type of flowmeter which integrates flow, temperature, pressure sensors .It is also a positive displacement, rotary type gas meter designed for continuously measuring and indicating the accurate measurement of gas in a pipeline. It is widely used in the measurement of non-corrosive gases such as natural gas, city gas, propane, nitrogen, industrial inert gas, etc.


2.Main features

1) Low initial flow rate: the min initial flow rate can reach 0.04m3/h;
2) High accuracy and repeatability: accuracy is not affected by medium, long-term operation and stable accuracy;
3) Low pressure loss: the pressure loss is 0.08 kPa-0.58 kPa;
4) Subsection correction: according to the flow frequency signal, the flow coefficient can be automatically linearly corrected in six sections to improve the wide range accuracy of the flowmeter;
5) It has the function of real-time data storage, and the internal data can be stored permanently in the power failure state.
