Water Flow Sensor Circuit
The sensor gives out frequency directly proportional to water flow.
Water flow sensor circuit. When water flows through the valve it rotates the rotor. The water flow sensor for flow rate volume measurement using arduino works on the principle of the hall effect. Water flow sensor as the name suggests is a device to measure the flow of water. Water flow sensor consists of a plastic valve from which water can pass.
The water flow sensor is integrated with a magnetic hall effect sensor which generates an electric pulse with every revolution. This water flow sensor has only three wires and it can be easily interfaced between any microcontroller and arduino board. 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. 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 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. A water rotor along with a hall effect sensor is present the sense and measure the water flow. When rotor rotates magnetic field cuts the sensor and when it comes in perpendicular electrical pulses are generated.
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. By this the change can be observed in the speed of the motor. The water flow sensor consists of a plastic valve body a water rotor and a hall effect sensor. The 5v is red coloured wire the black one is gnd and yellow one is output.
Yf s201 is a hall effect based water sensor. It has three terminals 5v nominal working voltage gnd and output. The hall effect sensor outputs the corresponding pulse signal. It has three wires namely 5v red gnd black and output yellow.
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. In water flow meter a small fan wings like rotor is placed in way of fluid. Yf s201 water flow sensor. Make sure to select one that will cover your needs.
When the water flows through the rotor rotor rolls and the speed of it changes with a different rate of flow. It has a plastic valve body with a rotor and a hall sensor circuit. The picture of the yfs201 sensor module alone is shown below.
