Working principle :

Fluid flows through the sensor shell, because the blade of the impeller has a certain angle with the flow direction, the impulse force of the fluid makes the blade have a rotational torque, and after overcoming the friction torque and fluid resistance, the blade rotates, and the rotational speed is stable after the torque is balanced, under certain conditions,the rotational speed is proportional to the velocity, it is in the magnetic field of the signal detector (composed of permanent magnetic steel and coil). the rotating blade cuts the magnetic fieled line and periodically changes the magnetic flux of the coil, thereby inducing electrical pulse signals from both ends of the coil. the signal is amplified and shaped by the amplifier to form a continuous rectangular pulse wave with a  certain amplitude, which can be transmittered far to the display instrument. shows the instantaneous flow and cumulative volume of the fluid . within a ceratin flow range, the pulse frequency is proportional to the instantaneous flow of the fluid flowing through the sensor ,and the flow equation is Q=3600*F/K
