Simple and versatile model.

The flow switches are used to control the flow in tubes and pipes in which waters, oil, chemical products, etc. are used.

The devices are supplied with 4 paddles kit for pipes to use it in pipes with a diameter from 1 " to 8 ".

When the liquid flow of the pipe pulls the Stainless Steel paddle actuates a microswitch. This microswitch is inside the plastic housing where there is and adjustment of the sensitivity.

The switch can be side or vertically mounted and the arrow in the proccess connection has to be faced to the flow.

The thread of the switch is G 1 " tappered. Mount the indicator in a screwed pipe, screwed into a “T” or into a welded couling of pipes with a diameter from 1 " to 8 ".

The indicator can be used in pipes with higher diameter depending on the application.

For a proper function, the device must be installed in straigh pipes with a mininum length at least of five times the diameter and far from valves or filters to avoid turbulence.
