The Worcester Bosch flow switch assembly for use in Heatslave units. The flow switch or flow metre has an inbuilt sensor that sits inside the heating or hot water system pipework as an important safety mechanism. It is designed to sense water flow. The switch feeds information to the boiler's printed circuit board to ensure that the burner is not activated when the system is low on water or dry.
