Abstract: An ultrasonic measuring device for the measurement of a flow of a fluid, includes a measuring tube, a first chamber and a second chamber. The measuring tube has a central axis, which defines a flow direction for the fluid; The first chamber has a first ultrasonic transducer arranged therein. The second chamber has a second ultrasonic transducer arranged therein. The measuring tube includes an inlet and an outlet for the fluid. The first ultrasonic transducer and the second ultrasonic transducer bound a rectilinear measuring section for the fluid, the first chamber and the second chamber being configured and arranged such that the fluid is capable of flowing around each of them. The first ultrasonic transducer and the second ultrasonic transducer are arranged such that the measuring section extends in the flow direction.

Abstract: An ultrasonic measuring includes a housing having a measuring channel and ultrasonic transducers. The housing is releasable attached to a pipe such that the measuring channel is capable of receiving the pipe and fixing the pipe with respect to the housing. The ultrasonic transducers emit and receive ultrasonic signals, and include first and second ultrasonic transducers. The first ultrasonic transducers define a first measuring section so as to be capable of exchanging ultrasonic signals, and the second ultrasonic transducers define a second measuring section so as to be capable of exchanging ultrasonic signals. The ultrasonic transducers are aligned such that the first and second measuring sections extend obliquely to a flow direction, and such that a measuring plane is defined by a center axis of the measuring channel and is different from a measuring plane defined by the center axis of the measuring channel and the second measuring section.
