YFS401 Coffee Machine Flow Meter Water Flow Sensor Connected to 6mm Hose Water Purifier Hall Sensor

YF-S401 Coffee Flow Connected to 6mm Hose Water
1. The water flow sensor is mainly composed of a plastic valve body, a water flow rotor assembly and a Hall sensor. The sealing ring is made of nitrile rubber imported from Japan, and the upper and lower force structure prevents water leakage.
2. It is installed at the water inlet end of the water heater to detect the water flow rate. When the water passes through the water flow rotor assembly, the Hall Elements is imported and sealed with potting glue to prevent water ingress and aging
3. The magnetic rotor rotates and the speed changes with the flow rate, and the Hall sensor outputs corresponding pulses
4. The signal is fed back to the controller, and the controller judges the size of the water flow and regulates it
5. The impeller is inlaid with a stainless steel shaft, which penetrates up and down to disperse stress points forever

1. The lowest rated working voltage: DC3.5 5V-12V
2. Maximum working current: 15 mA (DC 5V)
3. Operating voltage range: DC 5~18 V
4. Load capacity: ≤10 mA (DC 5V)
5. Operating temperature range: ≤80 Celsius
6. Operating humidity range: 35%~90%RH (no frosting state)
7. Allowable pressure resistance: water pressure below 1.75Mpa
8. Storage temperature: -25~+80 Celsius

Lead wire method:
1 Red IN to positive
2 Yellow OUT signal output line
3 Black GND connect to negative pole
4 Green R Temperature sensor
Frequency: F=5.5*Q(L/Min)-3 Error: ±2% Voltage: 3.5-24VDC, current cannot exceed 10mA, output 330 pulses after flowing one liter of water
That is, frequency calculation = constant 5.5 * unit flow (L/min) * time (seconds) -3
