Abstract

A measurement device for ascertaining a pressure in a measurement volume which receives a fluid or through which fluid flows. The measurement volume is bounded at least sectionally by a side wall and a vibration transducer is arranged on the side wall. The vibration transducer is actuable by a control device of the measurement device to excite a wave that is guided through the side wall. The guided wave is able to be guided through the side wall along a propagation path back to the vibration transducer or to at least one further vibration transducer and it is captured there by the control device in order to ascertain measurement data. The pressure in the measurement volume is then ascertained by the control device in dependence on the measurement data.
