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.

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