H-ADFM - Horizontal Acoustic Doppler Flow Meter (ADCP)

The H-ADFM is a revolutionary flow meter that has set new standards for flow measurement accuracy in wide channels and has made pulse doppler technology available for open channel applications with a width of 10ft or greater. The H-ADFM mounts on the side of a channel which allows easy access for maintenance. It measures the horizontal distribution of velocity within the flow, across the channel, using pulse doppler velocity profiling technology. Horizontal profiling increased information on the flow conditions and velocity structure that can not be provided from a single point surface measurement

The H-ADFM is the most versatile and most accurate flow meter available for metering sites in open channels and very large pipes including chlorine contact basins and other applications with rapidly changing, non-uniform, near zero, zero , reversed or backwatered flow conditions.The H-ADFM sensors can also be 'stacked' to provide horizontal profiles at multiple depths in the flow, providing superior data quality and increased accuracy eve in difficult hydraulic conditions.

Standard Features of the H-ADFM include:

  • Submersible sensor (to 100ft)
  • Pulse doppler velocity profiling technology
  • Real-time data output
  • Upward looking depth sensor and redundant cross-channel velocity sensors combined in one housing
  • Processing and sensor electronics in a single module
  • Data quality verification information (correlation and signal strength)
  • Stainless steel mounting bracket for installation on side of channel.
  • Rugged construction

Applications

  • Wastewater treatment facilities
  • Wastewater collection systems
  • Combined sewer systems and outfalls
  • Industrial discharges and process
  • Stormwater conveyance and outfalls
  • Irrigation canals and channels

Options and Accessories

  • Secondary depth sensor (ultrasonic or pressure)
  • Industry standard communications protocol interfaces
