Changes in velocity profile due to obstruction, deposits, pipe configuration, upstream and downstream lengths, wall roughness, roundness, plat condition, dP sensing taps will affect the orifice meter measurement.

Fluid properties such as Density, expansion factor, viscosity etc. can affect the results.

In addition, operating conditions such as flow variation and pulsating flow can have great influence on the Orifice meter measurement.
