A Glow-worm flow switch sensor for Ultracom2 appliances. The flow switch, or flow meter, has an inbuilt sensor that sits inside heating or hot water system pipework as an important safety mechanism. Designed to sense water flow, the switch feeds information to the boiler's printed circuit board (PCB) to ensure that the burner is not activated when the system is low on water or dry.
Please always refer to the manufacturer's instructions for the correct application. All parts should be fitted by a qualified plumber.
