NOTICE
To access the product datasheet, select the Rosemount Liquid Ultrasonic Flow
Meter link, click the Documentation tab, expand the Data Sheets - Bulletins -
Catalogs tab, then select the Data Sheet.
Meter tube dimensions with tube bundle or profiler plate for uni-directional and
bi-directional flow, the minimum straight pipe length is as follows:
Table 2-2: Piping recommendation for uni-directional or bi-directional flow
Uni-Directional Flow
8D up stream (with a flow conditioner)
8D up stream (no flow conditioner)
5D in front of flow conditioners if used
•
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 Rosemount Liquid Ultrasonic Flow Meter should be mounted in horizontal
piping with the chord paths horizontal.
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.
