Water Tank Level Controller for Fast Mains Water Tank Filling and Top-up

For use with automatic pumps to top-up Rainwater Harvesting Tanks with mains water.

The 3P TCS5JB Top-up Switch is intended to maintain the level of water in a water tank by topping up the tank when the level becomes low, with a measured amount of mains water.

Water level in the tank is sensed via a float switch, mains water is added via a high flow solenoid valve feeding back to the rainwater tank.

The solenoid will be activated when the float switch hangs down at approximately 45  or more, the top-up cycle will then continue until the float switch reaches an upward angle of approximately 45 degrees, ensuring a measured quantity of water is introduced to the tank.

1/2” version (pictured above) is supplied with a tundish and mounting bracket meeting the requirements of BS EN 13076, versions 3/4” and above require an air gap to be formed during installation.

A 24vdc version of this top-up controller is also available.
