what are the installation requirement is common to all flow
meter when volumetric flow rate is being measured
Answer / carl_ellis
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.
