[0002] The turbine flowmeter is an instrument that measures flow based on turbine rotation. It is mainly composed of turbines, magnets, sensors, counters and other components. When the fluid passes through the turbine, it will exert force on the turbine to make it rotate. The speed of the turbine is proportional to the flow rate of the fluid, that is, the greater the flow rate, the faster the turbine speed.
