摘要： Flowmeter comprising at least two ultrasonic transducers that are mounted on a container which is penetrated by a medium in a certain direction of flow. The ultrasonic transducers alternately transmit and receive ultrasonic test signals in the direction of flow and counter to the direction of flow. The flowmeter further comprises a control/evaluation unit which determines and/or monitors the volume flow of the medium inside the container based on the difference in the travel time of the ultrasonic test signals propagating in the direction of flow and counter to the direction of flow. The ultrasonic transducers are configured such that they transmit and receive ultrasonic test signals or sound fields having a large aperture angle or a great beam expansion.

摘要： A method for ascertaining volume- or mass-flow of a medium in a pipeline, or measuring tube, of radius (r) via a sound entrainment method, wherein ultrasonic measuring signals are transmitted and/or received along a plurality of defined sound paths (m). During a calibration phase, successive, different flow profiles (v(r)) of a measured medium are established in the pipeline, or in the measuring tube, and wherein, for each flow profile (v(r)), a defined volume flow, or a defined mass flow, is ascertained, wherein, on the basis of measured values (vx(r1) . . . vx(rm)) ascertained in the separate measuring paths (m), each flow profile (v(r)) established in the pipeline, or in the measuring tube, is described by a characteristic parameter set (a1, . . . , an with nεN) and wherein, for each flow profile (V(r)), on the basis of the defined volume- or mass-flow and on the basis of the measured volume- or mass-flow, a flow-profile-dependent correction factor MF(a1, . . . , an) is calculated, and wherein, subsequently in measurement operation, a volume- or mass-flow ascertained via the parameter set (a1, . . . , an, with nεN) is corrected with the flow-profile-dependent correction factor MF(a1, . . . , an) determined during the calibration phase.
