Abstract

A method for diagnosing a differential pressure line of a differential pressure measurement arrangement includes capturing a first set number of differential pressure values, which represent a difference between a first media pressure and a second media pressure within a process, and checking whether the differential pressure measurement arrangement and/or the process are in a state that allows a diagnosis of the differential pressure line. Where it is determined that the differential pressure measurement arrangement and/or the process are not in a state that allows a diagnosis of the differential pressure line, the differential pressure values are captured anew such that the previously captured differential pressure values are deleted or overwritten. Otherwise, a diagnostic function to determine whether a differential pressure line is blocked is carried out.
