Feature
●The water flow sensor is mainly composed of a plastic valve body, a water flow rotor assembly and a Hall sensor.
●It is installed at the water inlet end of the water heater to detect the influent flow rate as it passes through the water flow rotor assembly.
●The magnetic rotor rotates and the rotational speed changes with the flow rate change.
●The Hall sensor outputs a corresponding pulse signal and feeds it back to the controller.
●The controller determines the magnitude of the water flow and performs regulation.

Product features:
1. The product is light and flexible in appearance, small in size and easy to install.
2, the inside of the impeller is set with stainless steel beads, always wearable.
3. The sealing ring adopts the upper and lower force structure and never leaks.
4, Hall components are imported, and use waterproof rubber ring silicone to strengthen the prevention of water, never aging.
5. All raw materials are in compliance with ROHS testing standards
6, the standard G1/2 screw interface installation is simpler and firmer.
Lead line method:
1 red IN is connected to the positive
2 yellow OUT signal output line
3 black GND is connected to the negative
Frequency: F=7.5*Q(L/Min) Error: ±2%
At a flow rate of 1 L/min, 7.5 * 1 * 60 is equal to the number of pulses flowing through 1 liter of water. Voltage: 3.5-24 VDC, the current cannot exceed 10 mA, and 450 pulses are output after one liter of water. That is, frequency calculation = constant 7.5 * unit flow rate (L / min) * time (seconds)
Flow range: 1-30L/min
Precautions for use:
Severe impact and chemical attack are strictly prohibited.
It is strictly forbidden to throw or collide.
The temperature of the medium should not exceed 120 degrees
