DN15 G1/2 Water Flows Sensor Food-Grade Switch Hall Effect Flowmeter Fluid Meter

Describe According to the different control methods of the switch it can be used in two ways: water supply and power supply or water supply and power supply. It can be used for the control of water supply and electricity supply of fast electric water heater and the control of water supply and power supply of water storage type electric water heater. Working principle: When there is water flowing in the water flow switch and the water flow rate is ≥1.0L/min the magnetic core in the water flow switch is displaced by the water flow and the displacement of the magnetic core drives the magnetic source to produce a magnetic control effect so that the water flow switch outputs an on signal. The signal is input to the equipment control system and the control system realizes the control function. When the water flow is less than the starting flow the water flow switch outputs a off signal. The control system produces the opposite control actions to the above.
