YF-S401 Water Flow Sensor Coffee Machine Flowmeter Connected To 6mm Hose Water Purifier Hall SensorItem NO.: YF-S401

YF-S401 Water Flow Sensor

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 end of the water heater to detect the water inlet flow. When the water passes through the water flow rotor assembly, the magnetic rotor rotates and the speed changes with the flow. The Hall sensor outputs the corresponding pulse signal and feeds it back to the controller, which judges the water flow and regulates it.

Product Parameters:

● Minimum rated working voltage: DC3.5 5V-12V

● Maximum working current: 15 mA (DC 5V)

● Operating voltage range: DC 5 ～ 18 V

● Load capacity: ≤ 10 mA (DC 5V)

● Operating temperature range: ≤ 80 ℃

● Operating humidity range: 35%~90% RH (no frost)

● Allowable pressure resistance: water pressure below 1.75Mpa

● Storage temperature: - 25~+80 ℃

● Storage humidity: 25% ～ 95% RH

● Frequency: F=5.5 * Q (L/Min) - 3

● Error: ± 2%

● Voltage: 3.5-24VDC, current cannot exceed 10mA, and 330 pulses are output after one liter of water flows

● Frequency calculation=constant 5.5 * unit flow (L/min) * time (s) - 3

Product Features:

1. The product is light and convenient in appearance, small in size and easy to install

2. The impeller is embedded with stainless steel shaft, which can penetrate the upper and lower parts and disperse the stress points for permanent wear resistance

3. The sealing ring is made of NBR rubber imported from Japan, and the structure under upper and lower stress never leaks

4. Hall element is imported and sealed with potting glue to prevent water ingress and never aging

5. All raw materials comply with ROHS testing standards

Precautions:

● Severe impact and chemical erosion are strictly prohibited.

● No throwing or collision is allowed.

● The medium temperature should not exceed 120 ℃

Outgoing Line Mode:

1 red: IN connected to positive pole

2 Yellow: OUT signal output line

3 Black: GND connected to negative pole

4 Green: R temperature sensing (3950K 50K or 3950K, please choose according to your requirements)
