Elecro Electric Flow Switch

The Elecro electric flow switch is a safety flow sensor designed for electric pool water heaters. The switch detects water movement in the pipe and cuts off power to the heating element when circulation stops, thereby protecting the heater against overheating and dry-run damage. Installing the switch is a condition for the safe operation of inline electric heaters – without it, the heating element could overheat and fail or cause a fire in the event of a pump failure. The switch is installed in the supply pipe upstream of the heater and is connected to the heater’s control input. Compatible with Elecro heaters of the FlowLine and G2 series.
