摘要： This mass flow sensor has a vibration-body arrangement through which flows a fluid to be measured and which comprises the following parts: two plane, congruent tube loops each consisting of a straight inlet tube with an inlet end, a straight outlet tube with an outlet end, which ends are fixed in a common mount, and a tube bend interconnecting the respective inlet tube and the respective outlet tube. Mounted at the junctions of the respective inlet and outlet tubes and the associated tube bends is a plate with holes which correspond to the outside diameter of the straight tubes and the tube bends and in which the latter are fixed to determine a respective vibration node. A vibration exciter sets the two tube bends into opposite sympathetic vibrations perpendicular to their respective planes, and two sensors are spaced along the straight tubes for sensing the vibrations of the latter.

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.

摘要： A method serves to adjust a mechanical natural frequency of a hollow body which at least partly comprises a ductile material, in particular a pickup housing of a measurement pickup or a measurement pipe of a measurement pickup. A static external pressure of an atmosphere surrounding the hollow body and/or a static internal pressure prevailing in a lumen of the hollow body, the lumen being sealed off substantially in a pressure tight fashion, is varied in order to generate a pressure difference between the lumen and the atmosphere surrounding the hollow body. The pressure difference is adjusted to a value that causes the material of the hollow body to expand, and at least a proportion of the material of the hollow body is made to flow under the influence of the pressure difference for plastically deforming the material. The method can readily be integrated into already-established pressure tests for measurement pickups of the vibrational type.

摘要： This method of fastening a metal body to a an outer circumference of a single straight measuring tube, consisting of titanium or zirconium, of a Coriolis-type mass flow sensor does not need any heating, for example soldering, welding or brazing, process. The metal body has a circumferential surface and a bore adapted to the outer circumference. The metal body cooperates with an exciter arrangement or with a sensor arrangement or serves as a cantilever mass or as an end piece of the measuring tube. The metal body is pushed on to the measuring tube and is subsequently pressed on to the latter at ambient temperature. A pressure sufficient for fastening but not reducing substantially the lumen of the measuring tube at the fastening position is exerted on at least part of the circumferential surface.

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.
