Explosion-proof and corrosion-resistant flow switches for hazardous chemical process lines, reactors, and storage systems.

Common Applications

  • Cooling water supply and return to reactors and heat exchangers
  • Pump discharge protection — dry-run detection
  • Chemical injection line flow confirmation
  • Lube oil and seal flush flow monitoring
  • Scrubber and quench water flow detection
  • Solvent and acid transfer line monitoring
  • Nitrogen purge and blanket gas flow confirmation

Recommended Series

E Series

Explosion-proof (Class I Group D) for Division 1 and Division 2 classified areas. Up to 600 PSI. The standard choice for most chemical plant applications.

H Series

High-pressure explosion-proof for service above 600 PSI — up to 10,000 PSI. Solid rod and flexure tube design eliminates bellows failure in high-pressure chemical service.

N Series + Teflon Option

For non-hazardous areas with highly corrosive media. Teflon-lined body and PTFE paddle provide excellent resistance to acids, caustics, and solvents up to 100 PSI.
