Monitor flow in 1/2" to 2" pipe, Explosion-proof

The SERIES V6 Flotect® Flow Switches is surprisingly compact, and specifically engineered to monitor liquid, gas, or air flows. Time tested in thousands of pipeline installations and processing plants around the world, this Series is Weatherproof, designed to meet NEMA 4 and Explosion-proof (listing included in specifications). 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.

Product Applications

Protects pumps, motors and other equipment against low or no flow
Controls sequential operation of pumps
Automatically starts auxiliary pumps and engines
Stops liquid cooled engines, machines and processing when coolant flow is interrupted
Shuts down burner when air flow through heating coil fails
Controls dampers according to flow
Signals alarm when emergency shower or eyewash station in use

Features

Leak proof body machined from bar stock
Choice of models in a tee with calibrated vane or field adjustable trimmable vane
Electrical assembly can be easily replaced without removing the unit from the installation so that the process does not have to be shut down
High pressure rating of 1000 psig (69 bar) with brass body and 2000 psig (138 bar) on the 316 SS body
Low flow model offers field adjustable set point
Easy installation with simply pipe insert via the tee & simple electrical switch connections
Unique magnetically actuated switching design gives superior performance
Features a free-swinging vane which attracts a magnet within the solid metal switch body, actuating a snap switch by means of a simple lever arm with no bellows, springs, or seals to fail
