The Challenge of Flow Disturbances on Meter Accuracy
Flow disturbances may cause flow meters to under-read or over-read. The degree and direction vary widely, depending on the metering technology and other factors. For instance, flow velocity can greatly change the effect. The faster the water is flowing in the presence of a disturber, the more violent the reaction to the obstruction or bend.

On the energy transfer to small disturbances in fluid flow
The “energy in a small disturbance” in a viscous compressible heat-conductive medium is defined as a positive definite quantity characterizing the mean level of fluctuation in the disturbance which, in the absence of heat transfer at the boundaries and of work done by boundary forces or body forces, and in the absence of heat and material sources, is a monotone non-increasing
