Far more versatile and easier to set up than your old mechanical float level switches which jammed after a few months in the wet environment or whose strings became tangled, Lower cost too

This new module is designed to work with pumps or my listed ball valves to fill or empty a tank. Add one of my GSM controllers & the controlling valve or pump can be kms away. Just lower 3 wires into the tank. One at the level of an upper and another at the lower preset level. The 3rd goes even lower. So easy to install.

In its simplest configuration it just provides an alarm if water is either present or not present. So use it in flood prone areas or bathrooms for the elderly etc or in your outdoor water tank to warn of low level. Using my GSM controllers the alarm can be sent to anywhere globally with GSM coverage. or just attach one of my low cost piezo buzzers and or LEDs for a local alarm

In its more usual configuration it constrains the water levels between upper and lower levels by operating a pump or a valve. For instance as soon as a sump is full, empty it to the lower level in a single operation. .
