Water Flow Control Valve Arduino

Arduino solenoid valve control circuit here shows the simple arrangement to interface a solenoid valve with arduino.

Water flow control valve arduino.

Hardware setup to control a solenoid valve with arduino solenoids are very commonly used actuators in many process automation systems. Most solenoid valves are not for continuous use. The first device is installed by city water supply services to control water pressure. For hooking up to an arduino a belimo flow valve one example vendor only seems appropriately named.

For no normally open it is exactly the contrary. If you power the magnet with the expected current voltage the valve will open and the water will flow. They take a 0 10 v input signal as control and will rotate the vale. When current is flowing in the magnet it creates heat.

The motorized valve in blue is installed in parallel with a manual valve. I installed the part on the top of the picture. These are commercial type valves used to control water in heater systems and such. There will be no interrupt signal seen at the pin 2 of the arduino and the count of the flow frequency will be zero.

Dc solenoid valves are available with 6v 12v 24v 120v 240v operating voltages. In this blog post i will show how to drive a water valve from a gardena water timer computer using arduino uno. If the output valve of the pipe is closed the output of the water flow sensor is zero no pulses. Now this is not the only variable.

Here circuit has a 12v dc solenoid and it is powered by an external supply. In our project we connected the water flow sensor to a pipe. The controller i used in this example is or better say was a t14e model. Main water entry is located on the bottom.

In this drawing the manual valve is opened and the motorized valve is therefore bypassed.
