The Rain Harvesting Tank Gauge shows the water level in a rainwater tank on an easy-to-read dial. A float inside the tank moves the black indicator as the level rises and falls, with adjustable red empty and green full markers for your tank.
The gauge mounts on top of a vented tank and can be read from the ground. Set the full marker to the bottom of the overflow outlet and the empty marker to the bottom of the pump outlet, following the installation guide. These reference points show the usable water level for your installation.
The attached float passes through a 32mm hole in the tank roof. Two supplied screws secure the gauge. Choose a position with a clear view of the dial and room for the float to move freely.
