Abstract

The invention relates to a method for operating a measuring device, especially a flowmeter. 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.
