This pressure gauge connects to your 13mm main circuit of your Irrigatia C-60-120-180 irrigation system. This way you can always know the pressure going to your microporous hoses. This is preferably 0.3 to 0.5 bar. With 1 look at your pressure gauge you know whether there is enough pressure to make all hoses work optimally. Since 0.3 to 0.5 bar is quite a lot to make your drippers work on the same system, it is best to connect a 4mm tap for the drippers so that you can slow down the pressure.

When you connect or remove additional watering units, you can always keep the pressure the same thanks to the manometer. You do this by adjusting the tap on your 13mm transfer hose (back to the water source).
