Second, Xiamen liquid turbine flowmeter works:

As shown, the fluid flows through the sensor housing, since the flow impeller blade with a certain angle, the momentum of the fluid has a rotational torque of the blade, the blades rotate after overcoming the friction torque and fluid resistance, the speed in the torque balance and stability, in magnetic field under certain conditions, speed and velocity is proportional, because the leaves have permeability, it is a signal detector (by the permanent magnet and coil), the rotation of the blades cutting magnetic field lines, periodically changing the coil of the magnetic flux, so that both ends of the coil induces an electrical pulse signal which is amplified shaping amplifier is formed with a certain level of continuous rectangular pulse wave, can be remote to the display instrument, showing the instantaneous flow rate and cumulative amount of fluid. In certain within the flow range, pulse frequency f and instantaneous flow of the fluid flowing through the sensor Q proportional to the flow rate equation is: Q = 3600 * f / k;

Where:

f- pulse frequency (Hz);

k- sensor meter factor (1 / m 3 ), Is given by a single calibration. In terms of (1 / L) as a unit

Q- instantaneous flow of fluid (operating condition) (m3/h) ;

3600- conversion factor.

Each sensor meter factor from the factory fill in the verification certificate, k value is set into supporting the display instrument, it can display the instantaneous flow rate and cumulative totals.
