​ADFM® Velocity Profiling Flowmeters

The ADFM® product family uses exclusive pulse-Doppler velocity profiling technology to measure the velocity distribution within the flow, delivering advanced flow measurement performance.

This capability makes ADFM flowmeters exceptionally versatile - and the most suitable choice for metering sites at large pipes and open channels, particularly those with non-uniform, rapidly changing, backwatered, near zero, zero, or reverse flow conditions.



accQpulse™ Velocity Profiler

The accQpulse™ Velocity Profiler brings unparalleled measurement precision and accuracy to flow rate measurement in many sizes of pipes and open channels. Its unique ability to measure velocity at multiple points makes it suitable for most applications including sites with non-uniform, rapidly changing, near zero, or reverse flow conditions...

H-ADFM® Velocity Profiler

The introduction of the revolutionary H-ADFM Flowmeter has made pulse Doppler technology available for open channel applications 10 feet in width and greater. The H-ADFM has set a new standard for flow rate measurement accuracy that previously was not attainable in wide channel applications... Read More


ADFM® Hot Tap Velocity Profiler

The ADFM Hot Tap Flowmeter provides precise and accurate flow rate measurement in full and pressurized pipe applications where the pipe ID is 18" (460 mm) or greater. The Hot Tap can be used in the difficult hydraulic conditions often found in force mains, siphons, process lines, and other full-pipe applications... Read More


accQcomm™ Digital/Analog Interface Module

The accQcomm™ digital/analog interface module accepts RS-232/RS-422 serial data from up to three ISCO ADFM® flowmeters (accQpulse™ Hot Tap, or H-ADFM) and converts the data into an industry-standard digital protocol (MODBUS or Ethernet) or industry-standard analog signal (4-20 mA)... Read More
