Meter tube dimensions with tube bundle or profiler plate for uni-directional and bi-directional
flow, the minimum straight pipe length is as follows:
• The bore of the mating piping should be within 1% of the meter inside diameter.
• The meter is provided with dowel pins to align the meter body bore with the bore of the
mating piping.
• The Daniel Liquid Ultrasonic Flow Meter should be mounted in horizontal piping with the
chord paths horizontal
• Normally, the meter body is installed so that the electronics assembly is on the top of the
meter. If there is insufficient space above the piping for this arrangement, the meter can
be ordered with extra long transducer cables for remote mounting or the meter housing
can be installed with the electronics assembly on the bottom.
• The mating piping should include temperature and pressure measurement connections
located a minimum of two nominal pipe diameters length down stream of the meter, or
per API MPMS 5.8.
• Piping requirements for field calibration of high viscosity, low Reynolds Number
applications is comprised of the upstream pipe section, CPA (Canadian Pipeline
Associates) flow conditioning plate, Venturi reducer section, ultrasonic meter and
downstream pipe section.

FAULTY METER INSTALLATION
Correctly install the equipment
If meter bodies are mounted or oriented differently than specified above, debris or gas may
collect in the transducer ports which could adversely affect the transducer signals, or cause
equipment damage.
