Abstract

The invention relates to a method for flow measurement in pulsating flows, wherein said method comprises the steps of: a) providing a flow meter (1) comprising an inlet (2) and an outlet (3), a flow channel (4) extending between said inlet (2) and outlet (3), a first mass flow sensor (6) located inside said flow channel (4), a control unit in communication with the first flow channel, b) repeatedly b1) acquiring a signal sample of the output signal from the mass flow sensor (6), b2) translating the signal sample to a mass flow value using a previously made calibration, and c) providing an output signal comprising the last mass flow value.
