Operation is simple and dependable with no mechanical linkage as the flow switch is magnetically actuated. The lower body
holds the flow vane and one magnet, which controls the switch actuating magnet in the separate upper housing. In most applications
the switch is normally off with the pipeline flow forcing the vane against the vane spring. As the flow decreases the vane spring pushes
back the vane, actuating the switch to signal an alarm or shutdown. Tees are available for installation in pipelines from 1/2″ to 2″, with
bushings added the unit is easily adapted to 1/4″ and 3/8″ piping.
