Low-voltage switchgear and controlgear - Control circuit devices and switching elements. Flow rate switchesWhat is BS EN 60947 5 9 Control circuit devices and flow rate switches about? BS EN 60947 5 9 is a British standard as a part of the IEC 60947 series that applies to flow rate switches that sense the rate of flow of gas, a liquid, or a granular solid. These switches change their output state if a pre set value for the speed of flow is exceeded. These flow rate switches are self contained, have semiconductor switching element(s) and are intended to be
