  • Product performance description

1.Product introduction: Water flow sensor is mainly composed of plastic valve body, water flow rotor assembly and Hall sensor. It is installed at the water inlet end of the water heater and is used to detect the water inlet flow rate. When water passes through the water flow rotor assembly, The magnetic rotor rotates and the speed changes with the change of flow rate, and the Hall sensor outputs corresponding pulses. The signal is fed back to the controller, and the controller determines the size of the water flow and regulates it.
2.Pinout method:
1) Red IN to positive 
2) yellow OUT signal output line 
3) Black GND connected to negative
3.Frequency: F = 7.5 * Q (L / Min) Error: ± 2%
4.Taking the flow rate of 1L / min as the column, that is 7.5 * 1 * 60 is equal to the number of pulses output through 1 liter of water. Voltage: 3.5-24VDC, the current cannot exceed 10mA, and 450 pulses are output after one liter of water is flowed. That is, frequency calculation = constant 7.5 * unit flow rate (L / min) * time (seconds) Flow range: 1-30L / min
6.Minimum rated operating voltage: DC4.5 5V-24V
7.Maximum working current: 15 mA (DC 5V)
8.Working voltage range: DC 5 ~ 18 V
9.Load capacity: ≤10 mA (DC 5V)
10.Using temperature range: ≤80 ℃

11.Using humidity range: 35% ~ 90% RH (without frosting)
