The HUB-40EX Flow Sensor is certified for hazardous areas by CSA (US & Canada), ATEX, and IECEx. It features a NEMA 4X enclosure to protect from environmental conditions and has an integrated swivel union, allowing users to rotate for easy wiring. The HUB-40EX puts out a square wave output signal with a duty cycle of approximately 50%, which is protected by a self-resetting fuse. The easy thread-in installation means you are up and running in minutes.

Available Outputs:

  • Frequency (square wave with 50% duty cycle)

EX Certifications:

  • CSA (US & Canada)
  • ATEX
  • IECEx
