The product
Working Principle:
For a fluid with a certain viscosity, the angular velocity (or pulse frequency) of the turbine is directly proportional to the instantaneous flow (or flow rate) of the fluid within the specified flow rate range. The edge of the turbine blade is equipped with a magnetic conductor, which is in the magnetic field of the signal detector. Rotating blades cut magnetic lines of force, periodically changing the flux of the coil so that electrical pulses are induced at both ends.The signal is amplified and reshaped to form a continuous rectangular pulse wave with a certain amplitude, which can be transmitted to the display instrument to calculate the instantaneous flow rate and the cummulative flow rate of the fluid, as shown in figure 2
