Hot Tap Closed Pipe Velocity Profiler datasheet 0 pages

The ADFM Hot Tap Flow Meter provides
precise and accurate flow rate measurement in
full and pressurized pipe applications where the
pipe diameter 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.
The ADFM Hot Tap is a variant of the standard,
open channel ADFM flow monitoring system.
The Hot Tap combines the widely used ADFM
pulse Doppler velocity profiling technology with
a unique sensor assembly suitable for insertion
into full, operating pipes.
The Hot Tap’s velocity profiling technology
enables accurate flow rate measurement without
the usual lengthy upstream and downstream
straight-line conditions required by other
technologies. It measures flow rate to within
±2% of actual flow rate in closed pipes, even in
difficult applications such as installations near
bends, short straight runs, near pumps, etc.
Installation is accomplished by inserting the
sensor into an industry standard two-inch tap
through the pipe wall. Installation is straightforward
and quick, providing easy access to the
sensor for routine inspection and maintenance
when needed. The Hot Tap is constructed of
robust materials insuring years of worry-free
operation.
The Hot Tap sensor uses standard ADFM
electronics for data processing, collection, and
storage. For customers already familiar with the
standard ADFM system, operating the Hot Tap
system will be intuitively easy. All standard
ADFM software, communication, and interface
equipment are available for the Hot Tap.
