摘要： By means of this process it is intended to achieve a high mechanical-geometric accuracy of bent tubes, and it is used for bending a measuring tube for a Coriolis mass flow rate sensor by means of a tube section of a predetermined length and by means of a two-piece press mold, which has been matched to both the measuring tube, which has an inner diameter and an outer diameter, and to the desired shape. To this end, a flexible support body is inserted into the tube section, which is fastened in a first end of the tube section in such a way, that the end is closed, and whose maximum outer diameter is less than the inner diameter of the tube section. The tube section is filled with a liquid which is subsequently permitted to solidify completely. The tube section filled with the support body and the solidified liquid is placed into the opened press mold, the latter is closed and the tube section is bent into the desired shape by this. The press mold is opened and the bent tube section is removed. The solidified liquid is permitted to melt and thereafter the support body is removed from the bent tube section, along with the melted liquid.

摘要： A Coriolis principle mass flow meter is provided which is insertable into a conduit of a given diameter so as to be axially aligned with the conduit and through which flows a fluid to be measured. The flow meter includes two measuring tubes each having the same inner diameter and the same wall thickness. The two measuring tubes are coupled to an inlet manifold and an outlet manifold. The inlet and outlet manifolds are coupled to an external support tube. The flow meter also includes an internal supporting element that is parallel to the measuring tubes. Opposite ends of the internal supporting element are coupled to the inlet manifold and outlet manifold, respectively. The internal supporting element has a thermal transition resistance to the fluid which is lower than the thermal transition resistance of the external support tube to the fluid.

摘要： The measuring transducer serves for registering at least one physical, measured variable of a flowable medium guided in a pipeline and/or for producing Coriolis forces serving for registering a mass flow rate of a flowable medium guided in a pipeline. For such purpose, the measuring transducer comprises: A transducer housing (71), of which an inlet-side, housing end is formed by means of an inlet-side, flow divider (201) having exactly four flow openings (201A, 201B, 201C, 201D) spaced, in each case, from one another and an outlet-side, housing end is formed by means of an outlet-side, flow divider (202) having exactly four flow openings (202A, 202B, 202C, 202D) spaced, in each case, from one another; as well as exactly four, straight, measuring tubes (181, 182, 183, 184) connected to the flow dividers (201, 202) for guiding flowing medium along flow paths connected in parallel. Each of the four measuring tubes opens with an inlet-side, measuring tube end into one the flow openings (201A, 201B, 201C, 201D) of the inlet-side, flow divider (201) and with an outlet-side, measuring tube end into one the flow openings (202A, 202B, 202C, 202D) of the outlet-side, flow divider (202). Additionally, the measuring transducer includes an electromechanical exciter mechanism (5) for producing and/or maintaining mechanical oscillations of the four measuring tubes (181, 182, 183, 184), wherein the exciter mechanism is embodied in such a manner, that, therewith, the measuring tubes are excitable pairwise to execute opposite phase bending oscillations in, in each case, a shared imaginary plane of oscillation (XZ1, XZ2). The measuring transducer of the invention is suitable, especially, for measuring a density and/or a mass flow rate of a medium flowing in a pipeline, at least at times, with a mass flow rate of more than 2200 t/h.

摘要： The measuring system of the invention comprises: A measuring transducer of vibration-type, through which medium flows during operation and which serves for producing oscillatory signals dependent on a viscosity of the flowing medium and/or a Reynolds number of the flowing medium; as well as a transmitter electronics electrically coupled with the measuring transducer for driven the measuring transducer and for evaluating oscillatory signals delivered by the measuring transducer. The measuring transducer includes: An inlet-side flow divider (201) with four, mutually spaced, flow openings (201A, 201B, 201C, 201D); an outlet-side flow divider (202) with four, mutually spaced, flow openings (202A, 202B, 202C, 202D); four, mutually parallel, straight, measuring tubes (181, 182, 183, 184) for conveying flowing medium, connected to the flow dividers (201, 202) for forming a tube arrangement having at least four flow paths for parallel flow; as well as an electromechanical exciter mechanism (4) for exciting and maintaining mechanical oscillations of the measuring tubes (181, 182). Each of the four measuring tubes opens with an inlet-side measuring tube end into a flow opening (201A) of the inlet-side flow divider (201) and with an outlet-side, second measuring tube end into a flow opening (202A) of the outlet-side flow divider (202), a third measuring tube opens with an inlet-side measuring tube end into a flow opening (201C) of the inlet-side flow divider (201) and with an outlet-side, second measuring tube end into a flow opening (202C) of the outlet-side flow divider (202) and a fourth measuring tube opens with an inlet-side measuring tube end into a flow opening (201D) of the inlet-side flow divider (201) and with an outlet-side, second measuring tube end into a flow opening (202D) of the outlet-side flow divider (202). The transmitter electronics feeds, by means of an electrical driver signal supplied to the exciter mechanism, electrical excitation power into the exciter mechanism, while the exciter mechanism converts electrical excitation power at least partially into torsional oscillations of the first measuring tube (181), opposite-equal torsional oscillations of the second measuring tube (182), as well as into torsional oscillations of the third measuring tube (183), opposite-equal torsional oscillations of the fourth measuring tube (184).
