LWGB-80

LWGB-80 works: a fluid flowing through the sensor housing, since the flow of the impeller blades are angled, the blade having a fluid momentum rotational torque to overcome the friction torque after rotating blades and fluid resistance, the speed in the torque balance and stability, Under certain conditions, the speed and velocity is proportional, because the leaves have a permeability, it is a signal detector (consisting of permanent magnets and coils) in a magnetic field, rotating blades cutting magnetic field lines, periodically changing the coil of the magnetic flux so that the 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 a certain flow range, pulse frequency f and instantaneous flow of the fluid flowing through the sensor Q proportional flow equation: Q = 3600 × f / k; Where: f-- pulse frequency [Hz]; k-- sensor meter factor [1 / m3], given by a single check. In terms of [1 / L] units Q-- instantaneous flow of fluid (operating condition) [m3 / h]; 3600-- conversion factor. Each sensor meter factor by the manufacturer to fill in the test certificate, k value is set into supporting the display instrument, it can display the instantaneous flow rate and cumulative total LWGB-80
