The VF series flow switches contain only one moving part which results in an extremely reliable option for flow sensing applications. All VF series have now been SIL 3 safety rated and can be configured for use with gas or liquid media rated. The VF series utilizes an internal float and magnet assembly that is displaced upon fluid flow, the displacement of the magnetic field relative to an externally fixed reed switch results in opening or closing of the electrical contacts. The inline construction and availability in various end fittings simplify integration of these products into systems.
VF Series Flow Switches Features:
- All-attitude or vertical mount
- Magnetic operation
- High purity construction
- Corrosion resistant materials
- Minimal dead leg
