The (mostly unstated and assumed) common requirement for all
commercial flow meters is a full pipe.

The presence of air or gas in a liquid line not only causes
an inaccuracy in the measurement, in many cases it can cause
the measurement to fail altogether.

A close second for common requirements is to avoid vertical
downflows for liquids.
