■ F21 SERIES PADDLE STYLE FLOW SWITCH     The F21 Series flow switch is a tough but highly     sensitive paddle style flow switch suitable for a     wide range of flow control applications in both hot     and cold liquids. The electrical housing of the     switch is a separate assembly and locks onto the     wet end of the switch. It can be easily and safely     removed for servicing, without disturbing the     electrical wiring. This unique feature, and the     inclusion of a built-in override make the F21 a     very versatile flow switch. In addition to the     standard microswitch models the F21 is available     fitted with reed switches for PLC, relay logic,     and telemetry applications. •   Read more
