Датчик расхода воды

Water flow sensor On following the principle of Hall Effect, our product has settled lots of technic defects wih advanced controlling method to detect water flow. It is compact sized with low starting level, featuring in stable performance, accurate measurement, acute reaction, convenient access, and etc. When the water flow pushes the rotor, its magnet shall generate a rotating magnetic field; and then the Hall sensor will find a pulse signal from the magnetic field transformation, and then deliver it to the output control circuit after transformation. The signal pulse frequency and water flow is proportional. SPECIFICATIONS Working medium: water Medium temperature:0 80°C Ambient temperature:-20 85°C Measuring range:1.0 30 L/Min Operating voltage:2.1 18 VDC Interface size: G1/2″or(dia.19mm) Formula: Q=f/C (Q:quantity L/min; f: frequency Hz; C: constant) Accuracy: ±10%(when the water flow is 1.0 30L/min) Pressure resistance: it shall appear no deformation, leakage nor harm when the pressure is 1.2Mpa for 1 minute. Installation position: to be put at the vertical or horizontal direction with ±5° tolerance
