I. Product Introduction:
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 of the water heater and is used to detect the influent flow when the water passes through the rotor assembly.
The magnetic rotor rotates and the rotation speed changes with the flow rate, and the Hall sensor outputs corresponding pulses
The signal is fed back to the controller, and the controller judges the size of the water flow for regulation.
Use cautions:
Severe impact and chemical attack are strictly prohibited.
Do not throw or bump.
Medium temperature should not exceed 120 degrees
Third, lead way:
1 Red IN to positive
2 yellow OUT signal output line
3 Black GND to negative
Frequency: F=7.5*Q(L/Min) Error: ±2%
In the column of 1L/min flow rate, it is 7.5 * 1 * 60 that is equal to the number of pulses flowing through 1 litre of water.
Voltage: 3.5-24VDC,
Current cannot exceed 10mA,
One liter of water is output to output 450 pulses
Frequency calculation = constant 7.5 * unit flow (L/min) * time (seconds)
Flow range: 1-30L/min
Application scope:
Suitable for water heaters, automatic water dispensers, and other flow metering equipment!
1, the lowest rated operating voltage DC4.5 5V-24V
2, the maximum operating current 15 mA (DC 5V)
3, working voltage range DC 5 ~ 18 V
4, the load capacity ≤ 10 mA (DC 5V)
5, the use of temperature range ≤ 80 °C
6, the use of humidity range 35% ~ 90% RH (no frost)
7, allow pressure water pressure below 1.75Mpa
8, save the temperature -25 ~ + 80 °C
9, save the humidity 25% ~ 95% RH
