• 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
CAUTION
FAULTY METER INSTALLATION
Correctly install the equipment. If meter bodies are mounted or oriented differently
than specified above, debris may collect in the transducer ports.
Failure to comply may cause equipment damage or adversely affect the transducer
signals.
• 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.
2.3.1 High Viscosity piping requirements
The piping requirements for High Viscosity meter applications are shown in Figure 2-5 .
CAUTION
HIGH VISCOSITY FLOW MEASUREMENT METER RECALIBRATION
In high viscosity meter applications, if the connection between the upstream meter
flange ( Figure 2-5 , Item D) and the Venturi reducer ( Figure 2-5 , Item C) is disassembled
or disturbed for any reason, the meter will need to be recalibrated in accordance with
Daniel recommendations. Alignment of this flange joint is critical in the performance of
the meter. It is recommended to consult Daniel Support for assistance when re-aligning
this joint.
Failure to recalibrate the meter and correctly reinstall the flanged joint will result in
faulty flow measurement.
