Operating Principle

When the fluid flows into the flow meter, it is rectified and accelerated by the integrated rectifier, and then acts on the turbine blades at a certain angle to the flow direction. After overcoming the mechanical resistance and fluid resistance, the turbine starts to rotate. When the rotation reaches a stable state, within a certain flow range, the gas flow is proportional to the turbine speed. The turbine speed is extracted by the sensor and then calculated by the converter, combined with the temperature and pressure inside the pipeline, so as to realize the calculation of the standard cumulative flow and standard volume flow.
