ABSTRACT:
An inline measuring device serves for measuring a medium, especially a gaseous and/or liquid medium, in a pipeline. It includes, a vibration-type measurement pickup and a measuring device electronics electrically coupled with the measurement pickup. The measurement pickup has at least one measuring tube vibrating during operation and communicating with the pipeline, an electromechanical, especially electrodynamic, exciter mechanism acting on the at least one measuring tube for producing and maintaining mechanical oscillations of the measuring tube, a sensor arrangement for producing at least one oscillation measurement signal representing oscillations of the measuring tube and having at least one oscillation sensor arranged on the measuring tube or in its vicinity, and a measurement pickup housing. In an inline measuring device of the invention, it is additionally provided that the measuring device electronics monitors a static internal pressure within the measurement pickup housing and/or a hermeticity of the at least one measuring tube.
