Model to be inserted in a pipe, can be side or vertically mounted.

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

There is a paddle inside the device. When the liquid flow of the pipe pulls the paddle actuates the contact.

The switch has to be insterted between a pipe using the thread proccess connection depending on the model.

The models can be side or vertically mounted due to a return spring meanwhile the others has to be inserted vertically.

The indication arrow in the body has to be faced to the flow.

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.
