Abstract
An ultrasonic measuring device for measuring properties of a medium located in a measuring tube includes a measuring tube wall and a measuring tube lumen. The measuring tube wall has at least one acoustic region designed to be excited into Lamb oscillations. A pair of ultrasonic transducers are located in a coupling region and are designed to excite Lamb oscillations or to detect Lamb oscillations in the respective coupling regions. The device also includes an electronic measuring/operating circuit. A supporting device is designed to support at least parts of the acoustic region against media pressure, and at least one supporting member is designed to absorb forces generated by media pressure. The supporting member has at least one decoupling device which is designed to reduce ultrasonic input from at least one associated acoustic region into the supporting member, and vice versa.
