Description

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 influent flow rate as it passes through the water flow rotor assembly.

The magnetic rotor rotates and the rotational speed changes with the flow rate and the Hall sensor outputs a corresponding pulse.

The signal is fed back to the controller, and the controller determines the magnitude of the water flow and performs regulation.

The sensor has three connections, two for power supply and one output (yellow). Flow rate can be easily calculated, a pulse is approximately 2.25ml. If it is positioned and calibrated correctly, the accuracy of approximately 10%.

Calculation formula: Flow rate (l / min) = Frequency (Hz) /7.5.

Output waveform diagram: square wave NPN pulse signal


Lead line method

1. red IN is connected to the positive pole

2. yellow OUT signal output line

3. black GND connected to the negative


YF-S201 frequency: F=7.5*Q(L/Min) Error: ±2% Voltage: 3.5-24VDC, current can not exceed 10mA, output 450 pulses after one liter of water

That is, frequency calculation = constant 7.5 * unit flow rate (L / min) * time (seconds)

Flow range: 1-30L/min

This product is mainly used in water heaters, water dispensers, automatic water vending machines, credit card machines, etc.

Product wiring: red +, black -, yellow for pulse signal output

Output signal: NPN pulse signal

Note: 1. Fully sealed means that the product is not only waterproof but also anti-steam, moisture-proof, anti-corrosion, etc. It can be completely immersed in water. It is generally used in the bathing equipment of the bathing hall. It is resistant to temperature, pressure, and cold. Can you live with any test 2, not completely sealed means to prevent water from flowing in, but can not prevent steam from entering, please friends to know what they need when buying, please contact customer service if it is completely sealed.
