Abstract: A mount for electrical leads to a vibration-type sensor and/or for coils on a vibration-type sensor. The mount includes at least one resilient first arm attached to a first sensing tube of the sensor and at least one resilient arm attached to a second sensing tube of the sensor. The two sensing tubes, which are caused to vibrate during operation of the sensor, form a double-tube arrangement having a longitudinal gravity line, which lies in an imaginary central plane extending between the two, preferably parallel, sensing tubes. The mount exhibits a first eigenmode of predeterminable mechanical resonance frequency, at which the first arm and the second arm oscillate pendularly essentially perpendicular to the central plane of the double-tube arrangement.

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: 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.
