I’m using a open sprinkler PI for my irrigation.
With a water tank and a pump. A this time I have a level meter installed which opens a solenoid valve to refill with supply water when the level is to low.
My problem is that I have no sensors to proof that the system is working.
I would like to have a water meter at the supply water and also a water meter with manometer after the pump.
Does anyone know a water meter for connection to the rasperry. and a pressure meter/manometer to show the pump is working
Thanks a lot
