Connected to the overflow outlet of the toilet cistern or tank by a ¾” BSP connection the Flowtel WC Cistern sensor collects the first drops of water flowing through the overflow pipe work in it’s internal chamber triggering the leak alarm on the FT 101A Overflow Monitoring Panel. The unit does not obstruct the flow of water, allowing the overflow to drain safely until investigated.

The unit was manufactured by Flowise Limited until 2007.
