The flow speed of a fluid () flowing in a conduit () is measured using at least one ultrasonic transducer (a-b) that is attached to the conduit wall () from the outside The transducer (a-b) has an oscillating body () that couples to a part region () of the conduit wall () that acts as a membrane of the ultrasonic transducer (a-b) that can vibrate. A coupling piece () whose cross-section is smaller than the cross-section of the oscillating body () is arranged between the membrane () and the oscillating body ().

Ultrasonic fluid flow measuring using an oscillating body and a coupling piece having a reduced cross section than the oscillating body

A device for measuring the flow velocity and/or the throughput of a fluid by means of ultrasound, with at least one ultrasonic transducer () arranged on the outside of a wall () of a pipeline () and in contact with the wall (). In order to provide an improved measurement device, with which the maintenance expense can be reduced and which has a greater measurement accuracy, a portion () of the wall forms a part () of the ultrasonic transducer.

Device for measuring the flow rate and/or the flow throughput of a fluid

An ultrasound converter, especially of the axial oscillating type, with at least one piezoelectric element disposed between two tensioning segments and at least one tensioning member which prestresses the piezoelectric element via the tensioning segments. The tensioning element is a ring-shaped tensioning spring the walls of which have at least one peripheral recess.
