Series V6 Flotect Mini-Size Flow Switch

Brand: Dwyer Instruments, LLC
Does not ship to Virginia, United States
The Series V6 Flotect® Flow Switch is surprisingly compact, and specifically engineered to moni tor 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" (12.70 to 50.80 mm). With bushings added the unit is easily adapted to 1/4" and 3/8" (6.35 and 9.53 mm) piping.
Features
  • A unique magnetically actuated switching design gives superior performance
  • 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
  • Leak-proof body machined from bar stock
  • Electrical assembly can be easily replaced without removing the unit from installation so that the process does not have to be shut down
  • Choice of models in a tee with calibrated vane or field adjustable trimmable vane
  • Easy installation with simple pipe insert via tee and simple electrical switch connections
  • High pressure rating of 1,000 psig (69 bar) with the brass body and 2,000 psig (138 bar) with the 316 SS body
  • The low flow model offers field-adjustable set point
