Flow switches are used to signal, control and regulate the flow in a pipeline, to control pumps, burners, alarm signals, motorized valves.

They work by means of a flexible pallet which, stressed by the flow, acts on a microswitch in switching sptd.

They must be installed by means of a threaded connection on sections of horizontal pipe, away from valves, elbows, drains or irregular flows.

The choice of the flow switch must be made based on the diameter of the pipe.

Power supply: inductive load: 3a to 250v ~

Resistive load: 10a to 250v ~

Standard Features

–  Max. flow may be five times normal flow. –  Positive stop eliminates fatigue effects of turbulence, vibration and flow surge on flow detecting element. –  Very low pressure drop – typically less than 1.0 psig at normal flow rate. –  Small size and low profile provides easy mounting in crowded installations. –  Power the driving coil of small ice cube relays as well as some 30A power relays. –  Switches 5VDC to 240VAC. –  Switch employs magnetic coupling. –  Can be used in ¾ inch to 6 inch pipe
