Series V7 Flotect Vane Operated Flow Switch

Brand: Dwyer Instruments, LLC
Does not ship to United States
The Series V7 Flotect® Flow Switch is an inexpensive range switch for use with compatible liquids to start or stop electronic operated equipment when flow or no-flow conditions occur.

Design is standard weatherproof, meeting NEMA 4X.
Features
  • 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
  • Lower body is machined solid metal bar stock assuring no leak points, no matter how long the unit is in service
  • Robust vane design is rigid and field trimmable for set point adjustment
