Abstract

A method for monitoring a pulsating flow, the pulsation activated by a pulsation source (1) having a predetermined frequency, at a supervision position a distance away from the pulsation source (1) wherein the steps of indicating a varying signal (100, 101) at said supervision position based on the flow during a time dependent on a pulse identification for the flow, analysing said varying signal (100, 101) regarding its frequency content to identify at least one frequency region, determining at least one value of the amplitude of said signal obtained at said analysis, and comparing, either directly or by means of an algorithm, said obtained value with at least one calculated limit and/or one adaptive limit of a normal operating flow amplitude value.
