Abstract
The invention relates to a method for determining the instantaneous rate of the mass flow of a flow of a fluid pulsating periodically at a frequency f, said method comprising the following steps: a) a pressure gradient in the flow over a certain period (P) is determined, b) the harmonic amplitude of the pressure gradient is calculated by means of Fourier transformation, c) the frequency f and the time t are converted into dimensionless numbers F, t and d) the rate of the mass flow is determined using a table from which at least one corresponding value describing the mass flow rate and/or a phase difference can be deduced for each dimensionless number F of the frequency f.
