Fluid flows through sensor housing 21, and since blade and the flow direction of impeller 22 have certain angle, the impulse force of fluid makes
Blade has rotating torque, the rear blade of moment of friction and fluid resistance is overcome to rotate, the stabilization of speed after equalising torque, one
Under conditions of fixed, rotating speed is directly proportional to flow velocity, and since blade has magnetic conductivity, it is in signal detector (by permanent-magnet steel and line
Circle composition) magnetic field in, the blade cuts magnetic line of force of rotation periodically changes the magnetic flux of coil, so as to make coil two
End induces electric impulse signal, this signal passes through the amplification shaping of amplifier, is formed with the continuous rectangular pulse of certain amplitude
Wave, can teletransmission to display instrument, show the instantaneous flow and cumulative amount of fluid.In certain range of flow, pulse frequency f
The instantaneous flow Q of fluid to flowing through sensor is directly proportional, and flow equation is：Q=3600 × f/k.In formula：F --- pulse frequency
Rate [Hz]；The instrument coefficient [1/m] of k --- sensor, is singly provided by verifying.If with [1/L] for unit Q=3.6 × f/
The instantaneous flow (under working condition) [m3/h] of kQ --- fluid；3600 --- conversion coefficient.
Hall sensor 11 sends signal to processor 13 by connecting line 12, and analysis is calculated by number by processor 13
According to being transferred to display device 14.
