Abstract

The invention relates to a method for operating a measuring device, especially a flowmeter, according to the preamble of claim 1. The aim of the invention is to simplify inspection if the sensors have been correctly installed. For this purpose, the installation state is detected by the sensors themselves, i.e. by sensing a corresponding sensor value and comparing it with characteristic data. The result of comparison is electronically evaluated and automatically estimated whether the characteristic data obtained match the comparative data within at least a defined tolerance.

Claims

1. A method for operating a measuring device, especially a flowmeter, characterized in that the installation state is registered by the sensors themselves, that is to say by sensing an appropriate sensor value, and is compared with characteristic data, and the result of the comparison is then evaluated electronically and an automatic estimation is made as to whether the currently obtained characteristic data agrees with the comparative data, at least within a given tolerance.

2. The method as claimed in claim 1, characterized in that the characteristic data is stored in a database.

3. The method as claimed in claim 1 or 2, characterized in that the characteristic data is stored as spectra or as variables derived therefrom, which are then compared.
