I have a sensor for water flow (bought replacement part from Saeco machine) and also sensor that measures the tank water temperature. The sensor is on a spring touching the bottom of the tank so that nothing has to be disconnected:) I also have a water level sensor which is a small plastic pipe mounted to the side of the tank. Inside it there is a floating magnet. On outside of the tank, there is a flat spring which pushes two reed switches to touch the side of the tank where the pipe is. This allows me to detect when water falls below acceptable level.
