Water Flow Sensor Circuit

It has a plastic valve body with a rotor and a hall sensor circuit.

Water flow sensor circuit.

According to the hall effect a voltage difference is induced in a conductor transverse to the electric current and the magnetic field perpendicular to it. It requires only 5v vcc and gives pulse output the sensor needs to be tightly fitted between water pipeline. Shaft of this structure has magnetic link with hall s effect sensor. Water flow sensor consists of a plastic valve from which water can pass.

It has three wires namely 5v red gnd black and output yellow. When water flows through the valve it rotates the rotor. This water flow sensor has only three wires and it can be easily interfaced between any microcontroller and arduino board. Yf s201 water flow sensor.

The water flow sensor is integrated with a magnetic hall effect sensor which generates an electric pulse with every revolution. The water flow sensor for flow rate volume measurement using arduino works on the principle of the hall effect. The sensor gives out frequency directly proportional to water flow. When rotor rotates magnetic field cuts the sensor and when it comes in perpendicular electrical pulses are generated.

Its design is in such a way that the hall effect sensor is sealed off from the water and allows the sensor to stay safe and dry. The yf s201 sensor can measure from 1 litre minute to 30 litre minute. The 5v is red coloured wire the black one is gnd and yellow one is output. By this the change can be observed in the speed of the motor.

The bell gossett circuit sensor flow meter is a precision machined wafer type orifice insert that is installed between standard 125 150 250 or 300 psi ansi flanges to monitor system flow with a minimum friction head loss. It has three terminals 5v nominal working voltage gnd and output. Make sure to select one that will cover your needs. Water flow sensor as the name suggests is a device to measure the flow of water.

This type of sensor can be found on different diameters water pressure mpa and flow rate l m ranges. A water rotor along with a hall effect sensor is present the sense and measure the water flow. In water flow meter a small fan wings like rotor is placed in way of fluid. Yf s201 is a hall effect based water sensor.

The picture of the yfs201 sensor module alone is shown below. The hall effect sensor outputs the corresponding pulse signal. The water flow sensor consists of a plastic valve body a water rotor and a hall effect sensor.
