inferential flow meter

[¦in·fə¦ren·chəl ′flō ‚mēd·ər]
(engineering)
A flow meter in which the flow is determined by measurement of a phenomenon associated with the flow, such as a drop in static pressure at a restriction in a pipe, or the rotation of an impeller or rotor, rather than measurement of the actual mass flow.

Inferential flow meters infer volumetric flow rate by measuring one or more dynamic properties of the flowing gas stream.
Inferential flow meters use meter calibration factors or empirical coefficients to account for the effects of parameters that are not measured.
A critical factor in the use of inferential flow meters is to understand their sensitivity to distortions in the gas flow through the meter.
10 percent, and virtually no uncertainty for other inferential flow meters.
