Proof of Flow or No Flow in 1/2″ to 2″ Pipe, Low Cost, Leak Proof Body, Weatherproof

The Flotect Series V10 Flow Switch is designed to provide an inexpensive, reliable unit to monitor the presence or absence of flow in a system. The V10 flow switch is used to monitor unattended equipment and protect it from costly damage. The V10 flow switch utilizes a rugged, hermetically sealed reed switch which is encapsulated in a polypropylene switch housing that fits into a standard heavy duty leak proof brass body or optional 303 Stainless Steel body. The switch adjustment allows the user to change the switch to Normally Open (NO) or Normally Closed (NC) in the field merely by loosening two screws. The switch housing is located outside the process media, making switch change-over or maintenance easy without interruption of process flow.

A full size, trimmable stainless steel vane is provided with a removable laminated template. This template is calibrated for brass or ductile iron reducing tees and forged steel straight tee/bushing combinations. Allows for field installation in pipelines from 1/2″ to 2″ diameter.
