| Dwyer V8 Series Flotect Vane Operated Flow Switch |
Paddle flow switches or vane sensors with an electrical contact output are at a specific flow rate. Dwyer flow switches are economical and reliable. Applications include proof of boiler flow, air conditioning, controlling of dampers according to flow, and protecting pumps, motors and other equipment against low or no flow.
Dwyer V8 Series Flotect Features
- UL recognized as an industrial motor controller per UL standard 508, suitable for mounting in a protected environment
- Magnetically actuated switching design gives superior performance with free-swinging vane which attracts a magnet within the switch body, actuating a snap switch with no bellows, springs, or seals to fail
- Leak proof body and vane constructed of tough durable polyphenylene sulfide which has excellent chemical resistance
- A full size trimmable vane is provided with molded-in graduations
Application
- Chemical processing
- Air conditioning
- Refrigeration
- Heating systems
- Cooling lines
- Machinery
- Liquid transfer systems
- Water treatment
- Food processing
- Machine tools
