IEC 60947-5-9 Ed. 1.0 b – Low-voltage switchgear and controlgear – Part 5-9: Control circuit devices and switching elements – Flow rate switches
This part of IEC 60947 applies to flow rate switches that sense the rate of flow of a 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 connected to circuits, the rated voltage of which does not exceed 250 V 50 Hz/60 Hz a.c. or 300 V d.c.
