Publication number: 20070151370Abstract: The measuring transducer includes a transducer housing, as well as an internal part arranged in the transducer housing. The internal part includes at least one curved measuring tube vibrating, at least at times, during operation and serving for conveying the medium, as well as a counteroscillator affixed to the measuring tube on the inlet-side, accompanied by formation of a coupling zone, and to the measuring tube on the outlet-side, accompanied by the formation of a coupling zone. The internal part is held oscillatably in the transducer housing, at least by means of two connecting tube pieces, via which the measuring tube communicates during operation with the pipeline and which are so oriented with respect to one another, as well as with respect to an imaginary longitudinal axis of the measuring transducer, that the internal part can move during operation in the manner of a pendulum about the longitudinal axis.Type: ApplicationFiled: December 8, 2006Publication date: July 5, 2007Applicant: Endress + Hauser Flowtec AGInventors: Ennio Bitto, Christian Schuetze, Martin Anklin-Imhof, Christof Huber, Dieter Mundschin, Michael Lambrigger

Patent number: 7216549Abstract: A measurement transducer includes a transducer housing, which exhibits a multiplicity of natural oscillation modes and at least a first measuring tube for conveying at least a volume fraction of the medium to be measured. The measuring tube is held to oscillation in the transducer housing and vibrator, at least at times. Also included is an electromechanical, exciter mechanism acting on the at least one measuring tube and a sensor arrangement reacting to movements, i.e. bending oscillations, of the measuring tube. Also included is a first support element fixed, i.e. directly, to the transducer housing and serving for the formation of essentially locationally fixed oscillation nodes in the transducer housing for suppressing or erasing at least one natural oscillation mode of the transducer housing.Type: GrantFiled: November 4, 2005Date of Patent: May 15, 2007Assignee: Endress + Hauser Flowtec AGInventors: Alfred Rieder, Christian Schuetze, Martin Anklin-Imhof

Patent number: 7213469Abstract: A transducer has at least one at least temporarily vibrating flow tube of predeterminable lumen for conducting a fluid. The flow tube communicates with a connected pipe via an inlet tube section (103), ending in an inlet end, and an outlet tube section, ending in an outlet end, and in operation performs flexural vibrations about an axis of vibration joining the inlet and outlet ends. The flow tube has at least one arcuate tube section of predeterminable three-dimensional shape which adjoins a straight tube segment on the inlet side and a straight tube segment on the outlet side. At least one stiffening element is fixed directly on or in close proximity to the arcuate tube segment to stabilize the three-dimensional shape. By means of the at least one stiffening element, the cross sensitivity of the transducer is greatly reduced, so that cross talks from pressure to mass flow signals are minimized and the accuracy of the transducer is improved.Type: GrantFiled: May 2, 2006Date of Patent: May 8, 2007Assignee: Endress + Hauser Flowtec AGInventors: Alfred Wenger, Martin Anklin

Patent number: 7121151Abstract: The sensor includes at least one measuring tube for guiding a fluid The measuring tube an inlet end and an outlet end, and vibrating at least at times. The measuring tube communicates, by way of a first tube segment leading into the inlet end and a second tube segment leading into the outlet end, with a pipeline connected for allowing the fluid to flow through the measuring tube. The measuring tube is held oscillatably by means of a support, which is secured to the first tube segment by means of a first transition piece and to the second tube segment by means of a second transition piece. Especially for producing mass-flow-dependent, Coriolis forces and/or for producing viscosity-dependent frictional forces in flowing fluids, the measuring tube executes, during operation, mechanical oscillations about an oscillation axis (S) imaginarily connecting the two tube segments.Type: GrantFiled: November 30, 2002Date of Patent: October 17, 2006Assignee: Endress + Hauser Flowtec AGInventors: Martin Anklin, Rainer Lorenz
