A.3 Curve of the metering error, ET, as a function of
the pulsation amplitude, at low pulsation
amplitudes (for f = 5 Hz to 50 Hz)

Defines pulsating flow, compares it with steady flow, and indicates the requirements that allow accurate measurement of the mean flow rate in pipes where pulsations are present.
