Abstract

The invention relates to a method for monitoring a measurement device, in particular a flow measurement device, and to a measurement device itself. In order in this case to reliably preclude measurement errors resulting from incorrect installation, the invention proposes that a characteristic variable is calculated from a time series s(t) of the measurement signal of a measurement device and is compared with previously recorded reference values, with this being used as the basis to automatically generate a message as to whether the measurement device has been installed correctly or incorrectly.
