When the fluid to be measured flows through the turbine flowmeter sensor, under the action of the fluid, the impeller is forced to rotate, and its rotation speed is equal to the average flow velocity of the pipeline. In proportion, at the same time, the blade periodically cuts the magnetic lines generated by the electromagnet and changes the magnetic flux of the coil. According to the principle of electromagnetic induction, a pulsating potential signal, that is, an electric pulse signal, is detected in the coil, and the frequency of the electric pulsating signal is measured. The flow rate of the fluid is proportional.
