Abstract: This sensor, for a fluid and suitable for use in a pipeline at least temporarily containing the fluid flowing therethrough, has at least one curved measuring tube, which vibrates during operation and guides the fluid, and a housing enclosing the measuring tube. The housing is composed of a metal cap of two cap halves and a supporting tube, in which the measuring tube is held at its inlet and outlet ends in a manner such that the tube can oscillate, and out of which a measuring tube segment protrudes sideways. Each cap half has an edge with, in each case, four edge portions. The edge portions are straight, the edge portions are curved, and the edge portions have the shape of circular arcs. The edge portions are welded continuously to the supporting tube and the edge portions are welded continuously to one another. The cap halves are cut out of a dish-shaped intermediate having a formed, surrounding edge bead, provided with the shape of a quarter-torus by metal spinning.

Abstract: A 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.

Abstract: The magnetic circuit arrangement, which is preferably used in a fluid-measuring transducer, comprises at least one coil which is traversed in operation by a current. It further comprises two armatures that are fixed to two flow tubes vibrating in phase opposition. The coil is float-mounted by means of a holder to a double flow tube configuration formed by the flow tubes. The armatures are shaped and aligned relative to each other in such a manner that magnetic fields produced by means of the magnetic circuit arrangement are essentially concentrated within the magnetic circuit arrangement, whereby the latter is also largely insensitive to extraneous magnetic fields. The magnetic circuit arrangement is marked by a long service life and, particularly if the transducer is used for fluids with high and/or varying temperatures, by constantly high accuracy in operation.

Abstract: The magnetic circuit arrangement, which is preferably used in a fluid-measuring transducer, comprises at least one coil (13) which is traversed in operation by a current. It further comprises two armatures (11, 12) that are fixed to two flow tubes (211, 212) vibrating in phase opposition. The coil (13) is float-mounted by means of a holder (15) to a double flow tube configuration (21) formed by the flow tubes (211, 212). The armatures (11, 12) are shaped and aligned relative to each other in such a manner that magnetic fields produced by means of the magnetic circuit arrangement are essentially concentrated within the magnetic circuit arrangement, whereby the latter is also largely insensitive to extraneous magnetic fields. The magnetic circuit arrangement is marked by a long service life and, particularly if the transducer is used for fluids with high and/or varying temperatures, by constantly high accuracy in operation.

Abstract: This mass flow/density sensor (10), which can be installed in a pipe and through which a fluid to be measured flows during operation, is to be balanced over a wide density range, so that accurate measurements are possible. A single straight measuring tube (13) having a longitudinal axis (131) extends between its inlet end (11) and the outlet end (12) and is fixed to a support, e.g., a cylindrical tube (14, 14′). The support has a longitudinal centroidal line (141) which is parallel to, but does not coincide with, the longitudinal axis (131) of the measuring tube. A cantilever (15) is fixed to the measuring tube (13) midway between the inlet and outlet ends (11, 12) and in operation causes the measuring tube to vibrate either in a first fundamental flexural mode or in a second fundamental flexural mode having a higher frequency than this first mode. An excitation arrangement (16) disposed midway between the end pieces excites the measuring tube (13) in the second mode.
