What do you get by buying the Rainwater set?

Extreme drought of recent years forces us to look for alternative sources of water and also to manage it better. This set, specially designed for the simples possible installation, maximum functionality and maintenance-free operation for many years, will provide you with a constant overview of the rainwater level in your tank.

You will immediately see how much water has just rained, how much you used during the last watering, how much water is left in the tank. Thanks to the built-in relay, you protect the pump from running dry, you allow water from a well or water supply line. The version with two relays then allows independent control of two different devices.
