Choosing the transducer installation locations on the pipe is an
important aspect of proper flow measurement. Specifications
assume a fully developed flow profile typically requiring 20
diameters upstream and 10 diameters downstream of straight pipe
run. In addition, pipes 2 in. and under require an installation
location with a minimum of 10 ft (3 m) of continuous straight
pipe without flanges, welds or coupling joints.
