Water Flow Sensor Circuit

In water flow meter a small fan wings like rotor is placed in way of fluid.

Water flow sensor circuit.

Yf s201 is a hall effect based water sensor. The hall effect sensor outputs the corresponding pulse signal. The water flow sensor for flow rate volume measurement using arduino works on the principle of the hall effect. This water flow sensor has only three wires and it can be easily interfaced between any microcontroller and arduino board.

The water flow sensor used in this project is shown in the image below. Make sure to select one that will cover your needs. The water flow sensor is integrated with a magnetic hall effect sensor which generates an electric pulse with every revolution. When rotor rotates magnetic field cuts the sensor and when it comes in perpendicular electrical pulses are generated.

The water flow sensor consists of a plastic valve body a water rotor and a hall effect sensor. Yf s201 water flow sensor. 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.

It has a plastic valve body with a rotor and a hall sensor circuit. Water flow sensor as the name suggests is a device to measure the flow of water. A water rotor along with a hall effect sensor is present the sense and measure the water flow. 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.

Water flow sensor consists of a plastic valve from which water can pass. Shaft of this structure has magnetic link with hall s effect sensor. This type of sensor can be found on different diameters water pressure mpa and flow rate l m ranges. It requires only 5v vcc and gives pulse output the sensor needs to be tightly fitted between water pipeline.

The sensor gives out frequency directly proportional to water flow. When the water flows through the rotor rotor rolls and the speed of it changes with a different rate of flow. 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 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.

The b g 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. The picture of the yfs201 sensor module alone is shown below. By this the change can be observed in the speed of the motor.
