摘要： A measurement pickup includes at least four measuring tubes for conveying media to be measured. Each measuring tube has a first in-/outlet end and a second in-/outlet end. During operation, the measuring tubes vibrate, at least at times, especially simultaneously. The measurement pickup further includes an electromechanical exciter mechanism causing the measuring tube to vibrate, as well as a sensor arrangement reacting at least to local vibrations of the measuring tubes for producing at least one measurement signal influenced by vibrations of the measuring tubes. Of the at least four measuring tubes, two measuring tubes are, at least at times, inserted into the course of a first medium-line such that each of these two measuring tubes simultaneously conveys, in each case, a partial volume of a medium flowing through the first medium line, and two other measuring tubes of the at least four measuring tubes are, at least at times, inserted into the course of a second medium line such that each of these two measuring tubes simultaneous conveys, in each case, a partial volume of a second medium flowing through the second medium line. The measurement pickup can thus, on the one hand, have two media flowing through it, which differ measurably from one another in at least one physical property, for example mass flow rate, medium density and/or medium temperature, while having, on the other hand, despite the different media, a good zero-point stability.

摘要： 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 two arms of the mount are essentially rigidly connected to one another at a connecting location remote from the two sensing tubes, and the mount exhibits a first eigenmode of predeterminable mechanical resonance frequency, f1, at which the first arm attached to the first sensing tube and the second arm attached to the second sensing tube oscillate pendularly essentially perpendicular to the central plane of the double-tube arrangement. The mount exhibits a second eigenmode of predeterminable mechanical resonance frequency, f2, at which the first arm attached to the first sensing tube and the second arm attached to the second sensing tube oscillate pendularly essentially parallel to the central plane of the double-tube arrangement, and the resonance frequency, f1, of the first eigenmode is different from the resonance frequency, f2, of the second eigenmode.

摘要： 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.

摘要： 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. Sensors (17, 18) for the motions of the measuring tube on the inlet and outlet side are positioned between the middle of the tube and the inlet and outlet ends, respectively. The support may be provided with a counterbalance. Because of the torsional vibrations exerted by the cantilever on the measuring tube, the sensor is also well suited for measuring the viscosity of the fluid.

摘要： This mass flow sensor, which can be mounted by means of end parts, in particular flanges, in a conduit of a given diameter through which flows a fluid to be measured, has two parallel, circular-arc-segment-shaped measuring tubes which are fixed at their ends in respective flanges. The measuring tubes have the same inner diameter D and the same wall thickness w. The circular-arc segment has a height h, an arc radius R, and a chord length L. The inner diameter D is chosen as a function of the maximum permissible pressure loss in the measuring tubes, and the wall thickness w as a function of the maximum permissible pressure of the fluid. The stress .sigma..sub.T resulting from a maximum permissible temperature change .delta.T of the fluid is chosen to be less than the .sigma..sub.0.2 -value of the material of the measuring tubes. Under these conditions and for a given arc radius R, the segment height h is chosen as small as possible to become h.sub.min. An external support tube is provided whose ends are fixed to the respective end parts. Means are provided for exciting the measuring tubes into opposite sympathetic vibrations perpendicular to the respective circular-arc plane, and means for sensing, at at least two points spaced along the measuring tubes, the vibrations of the measuring tubes.

摘要： The measuring transducer includes at least one measuring tube communicating with a line connected during operation for conveying a medium to be measured, and a support element oscillatably holding the at least one measuring tube. Additionally, it is provided that the support element contains at least two passageways, via which the at least one measuring tube communicates with the line, and that the at least one measuring tube is affixed, especially releasably, at at least one end to the support element by means of a screwed-fitting at one of the passageways. Alternatively or in supplementation thereof, it is further provided that the at least one measuring tube is, at least in part, made of cold-strengthened, for instance cold-stretched or autofrettaged, material. As required, the measuring transducer can further include at least two measuring tubes communicating with the line for conveying the medium; each of these two measuring tubes is to be connected to an inlet-side distributor element and an outlet-side distributor element. In such case, at least one of the two distributor elements can be embodied as an integral component of the support element, so that the support element can be kept, at least in the area of this at least one distributor element, free of materially bonded, joined locations, especially free of solder, braze or weld connections. The measuring transducer of the invention is especially provided also for applications in which the medium to be measured acts with a pressure of more than 500 bar, especially over 700 bar, on the measuring tube.
