HUB-40EX Hazardous Area Flow Sensor

 AW Lake is a corporate from United States of America that sell some product such as Positive Displacement Meters, Turbine Flow Meters, Tricor Coriolis Flow Meter, Lake Variable Area Flow Meter, Lake Paddle Wheel Flow Meter "Flow Stat", Monitor&Controllers, Flow Sensor&Pickups. One of the product that comes from the categories of Flow Sensor&Pickups is HUB-40EX Hazardous Area Flow Sensor.

HUB-40EX Hazardous Area Flow Sensor

The HUB-4xEx is a frequency output, pickup sensor certified for use in explosion proof areas. The sensor detects the rotation of an approved flow meter’s gears and emits a frequency signal proportional to the flow. The output signal is a square wave pulse, which has a duty cycle of approximately 50%. MAG signal outputs are protected with a self-resetting fuse. This fuse has a 50 mA nominal trip point. When a trip occurs, turn off power to the sensor and remove output load to reset the fuse.

Ideal for any industry or flow measurement application where an explosion-proof sensor is required, such as in chemical injection, hydraulic fracturing, or industrial paint spray booths.


  • Choose from Hazardous area certification options including: cCSAus or ATEX/IECEx
  • Square wave output signal has a duty cycle of approximately 50%.
  • For use with all AW-Lake EX flow meters.


  1. 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.

  2. 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.

  3. Weather-Proof Enclosure

    NEMA 4X enclosure provides environmental protection from moisture and debris.

  4. Built-In Protection

    The signal outputs are protected by a self resetting fuse with a 50 mA nominal trip point.
