سنسور جریان آب Water Flow Sensor YF-S401

YF-S401 machine flow meter water flow sensor
product description
1. The water flow sensor is mainly composed of a plastic valve body, a water flow rotor assembly and a Hall sensor.
2. It is installed at the inlet end of the water heater and is used to detect the inlet water flow rate. When the water passes through the water flow rotor assembly.
3. The magnetic rotor rotates and the speed changes with the flow rate change.
The Hall sensor outputs the corresponding pulse signal and feeds it back to the controller. The controller judges the size of the water flow rate and adjusts it.
Precautions for use
Severe impact and chemical attack are strictly prohibited.
Throwing or collision is strictly prohibited.
Medium temperature should not exceed 120 degrees
Output waveform: square wave
Leading way
1 Red IN connected to positive
2 Yellow OUT signal output line
3 Black GND connected to negative
4 Green R temperature sensor (3950K 50K or 3950K, please choose according to your requirements)
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 rate (L/min) * time (seconds) -3
Features
1.The appearance of this product is light and handy, small in size, easy to install.
2. Inside the impeller is set with a stainless steel shaft, which penetrates up and down to disperse the stress points forever.
3. The sealing ring is made of nitrile rubber imported from Japan, and the structure under the force is never leaking.
4.The Hall element is imported and encapsulated with potting glue to prevent water ingress and never aging.
5. All raw materials comply with ROHS testing standards
