H-ADFM Horizontal Velocity Profiler0 pages

H-ADFM Velocity Profiler
for Wide, Open Channels
The unique H-ADFM Flow Meter makes pulseDoppler technology available for use in open
channel applications 10 feet or more in width.
The H-ADFM provides a degree of flow rate
measurement accuracy that was previously not
attainable in wide channel applications.
Pulse-Doppler velocity profiling technology
measures the horizontal distribution of velocity
within the flow, across a channel, delivering
information regarding the velocity structure and
flow conditions; that a single point measurement
on the surface – or in the flow – cannot.
The H-ADFM sensor mounts on the side of a
channel, allowing easy access to the system for
maintenance when needed. Additional
H-ADFM sensors can be positioned at
various levels within the flow. This gives
increased accuracy and superior data quality,
even in difficult hydraulic conditions.
The sensor’s advanced flow measurement
performance makes it the most versatile, precise,
and accurate choice available for metering wide,
open channels – particularly those with nonuniform, rapidly changing, backwatered, near
zero, zero, or reverse flow conditions.
