Abstract (en)

[origin: EP1298421A1] Fault monitoring method for a Coriolis mass flowmeter with at least two vibration sensors (17, 18), a vibration generator (16) and temperature sensor (19, 20) has the following steps: <??>(a) Monitoring of the input and output signals to the digital signal processor <??>(b) storage of fault reports together with the time of a fault occurrence <??>(c) classification of fault reports into two classes, i.e. device caused and operation caused <??>(d) localization of a device fault by function testing or by comparison of operating values with those stored previously.
