Request Information

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

Up and Running in Minutes
Easy thread-in installation. A quick setup procedure allows you to have the sensor working with just a few simple installation steps.

Flexible Mounting
Because of the integral swivel union, the HUB-40EX unit can be rotated 360° for easy wiring. Options available to fit any AW Gear Meter or Turbine Meter.

Weather-Proof Enclosure
NEMA 4X enclosure provides environmental protection from moisture and debris.

Built-In Protection
The signal outputs are protected by a selfresetting fuse with a 50 mA nominal trip point.
