TRH-L-Z Turbine Flow Sensor,Liquid flow calculation instrument


The water flow sensor is mainly composed of a copper valve body, a water flow rotor assembly, a steady flow component and a Hall element. It is installed at the inlet end of the water heater to measure the influent flow. As the water flows through the rotor assembly, the magnetic rotor rotates and the rotational speed changes linearly with the flow rate. The Hall element outputs the corresponding pulse signal to the controller, and the controller determines the magnitude of the water flow, adjusts the current of the proportional valve, and controls the gas volume through the proportional valve to avoid the phenomenon of summer warm and cool winter in the use of the gas water heater. . The water flow sensor fundamentally solves the shortcomings of the water pressure of the differential pressure type water-gas linkage valve and the dry burning of the flap type water valve. It has the advantages of sensitive, long life, quick action, safe and reliable, convenient connection and low flow rate (1.5L/min).
