摘要： A measured-value sensor for an inductive flowmeter comprises a fluid impermeable sintered ceramic measuring tube adapted to be positioned in a conductive-liquid flow path. Magnetic coils surround the tube and are adapted to apply a magnetic field to a conductive liquid traversing the path. A pair of diametrically opposite measuring electrodes contact the liquid traversing the path for tapping an induced voltage across the electrodes representing the flow of the liquid along the path, each of the electrodes having a metallic shaft traversing the tube substantially radially and sealingly sintered to the material of the tube. The ends of the ceramic measuring tube are provided with a flange, ground at its peripheral wall surface and fastened by shrinkage stress in a bore of a steel casing. After sintering of measuring tube, conductive paths are manufactured for the formation of grounding rings and other current-conducting components by applying a platinum paste on the ceramic measuring tube and reheating again subsequently. In the process, the paste compacts to form a thin conductor film which is firmly anchored on the surface of said measuring tube.

摘要： A measured-value sensor for a flowmeter of the type which can be connected in a pipeline traversed by the flow of a conductive material which has a ceramic tube in which a pair of ceramic electrodes of relatively high conductivity by comparison to the electrical conductivity of the remainder of the tube are fused and thereby integrated. A conductive ceramic ring in the form of a grounding ring may be fused to the tube at one end thereof.

摘要： The invention concerns a mass flow meter for flowing media that works on the Coriolis Principle, with at least one Coriolis line carrying the flowing medium, at least one oscillator exciting the Coriolis line, at least two transducers detecting Coriolis vibrations based on Coriolis forces and a control unit controlling the oscillator and evaluating the measurement signals from the transducers, wherein the oscillator excites the Coriolis line with an excitation power and wherein a generator is provided that supplies the excitation power to the oscillator. The mass flow meter is characterized by the fact that the excitation power of the generator can be adjusted during operation, so that the amplitudes of the excitation oscillation of the Coriolis line can be adjusted to the most optimal value possible.
