Description

The FLSW is the flow switch from IPS Controllers. It installs in the flow cell and gives the controller a positive signal that water is actually moving through the sample line.

Why the interlock matters

A chemical controller should only feed when there is flow to carry and dilute what it doses. If the pump is off and the controller keeps feeding, concentrated chemical pools in the line, which is hard on plumbing and equipment and does nothing for the water. The flow switch is the piece that makes feeding conditional on circulation.

What you get

This listing is the switch on its own. The flow cell that houses it is a separate item, so this suits an existing installation where the cell is sound and the switch has failed.
