The working principle of the turbine flow meter mainly relies on the power of the flowing fluid to drive the turbine blades to rotate. Within a certain flow range and for a certain fluid medium viscosity, the rotation angular speed of the turbine flowmeter is proportional to the fluid flow rate.  The mechanical part of a turbine type flow meter consists of a turbine rotor whose rotational speed depends on the flow rate. The higher the flow rate, the greater the number of revolutions of the rotor, and the higher the frequency of the electrical pulses generated. The frequency of this electrical pulse is proportional to the volumetric flow rate and can therefore be used to measure the volumetric flow rate. Turbine flow meters usually consist of turbines, magnets, sensors, counters and other components. The turbine type flow meter working principle is to estimate the volume flow rate of the fluid by measuring the rotation speed of the turbine blades. This turbine meter measurement method is suitable for a variety of fluid media, including liquids and gases, and has high measurement accuracy and response speed.
