Abstract: A method recognizes wear of a flow meter, involving measuring a baseline of a characteristic of the flow meter, operating under operating conditions, as a configuration, over a calibration period; forming an average value of the baseline, and defining a reference value, an upper limit, and a lower limit, based on the average value, and cyclically measuring the baseline of the characteristic, in a measuring over a measuring period, during wear-causing operation of the flow meter; forming the average value; comparing this average value to the upper and lower limits; and issuing a warning signal when the upper limit is exceeded or when the lower limit is fallen below.
