Abstract (en)
[origin: WO2018028931A1] A method for diagnosing a differential pressure line (3, 5) of a differential pressure measurement arrangement (1), in particular according to any one of the preceding claims, having at least the following method steps: a) capturing a first set number of differential pressure values (x1 …xn) which represent a difference between a first media pressure (p1) and a second media pressure (p2) within a process; b) checking whether the differential pressure measurement arrangement (1) and/or the process are in a state which allows a diagnosis of the differential pressure line; c) return to method step a) in the case where it is determined that the differential pressure measurement arrangement and/or the process are not a state which admits a diagnosis of the differential pressure line (3, 5), wherein, in the method step a), the differential pressure values are captured a new such that the previously captured differential pressure values(x1 …xn) are deleted or overwritten; d) carrying out a diagnostic function to determine whether a differential pressure line is blocked in the case where it is determined that the differential pressure measurement arrangement (1) and/or the process are in a state which allows a diagnosis of the differential pressure line (3, 5).
