Patent number: 8573026Abstract: 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 n?N) 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, . . .Type: GrantFiled: April 20, 2006Date of Patent: November 5, 2013Assignee: Endress + Hauser Flowtec AGInventors: Thomas Froehlich, Matthias Altendorf, Torsten Strunz

Patent number: 7469599Abstract: 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.Type: GrantFiled: October 15, 2003Date of Patent: December 30, 2008Assignee: Endress + Hauser FLowtec AGInventors: Thomas Froehlich, Achim Wiest, Torsten Strunz

Patent number: 7412902Abstract: A clamp-on ultrasonic flow measuring device for determining volume and/or mass flow rate of a medium in a containment. The clamp-on ultrasonic measuring device is of low temperature sensitivity. To this end, the coupling element, through which the ultrasonic measuring signals are coupled into, and/or out of, the containment, has at least two element portions, which are embodied and/or arranged in such a manner that the predetermined in-coupling angle into the containment and/or the predetermined out-coupling angle out of the containment are/is approximately constant over an extended temperature range.Type: GrantFiled: March 31, 2004Date of Patent: August 19, 2008Assignee: Endress + Hauser Flowted AGInventors: Achim Wiest, Andreas Berger, Torsten Strunz
