Water Flow Meter Sensor Hall effect Switch Water Valve

Flow meters can be used to measure quantity of water passing through liquid pipes. If water can be monitored so it can also be controlled hence some flow meters have special circuits with actuators through which we can control the water flow. Not only water, flow meters can be used to measure the volume of gas passing through the pipe. With gas volume, flow pressure can also estimated. Major constraints of flow meters are accuracy, precision and resolution. With out accuracy, precision and greater resolution flow meters are of no use.
