摘要： A support device (12) for a Coriolis mass flow meter/density meter fastens to inlet and outlet ends of a measuring tube (11) so as to let the tube vibrate. Test signals represent vibrations at the tube's inlet and outlet ends. An electronic evaluation unit generates an intermediate value from the test signals to represent an uncorrected mass flow rate and a corrected value. An independent claim is also included for a method for using a Coriolis mass flow meter to generate a measurement value representing mass flow of a medium flowing in a pipe line.

摘要： Disclosed is a Coriolis mass flowmeter/density meter comprising at least one measuring tube (11) through which a two-phase or multiphase medium flows during operation thereof. A supporting means (12) of the Coriolis mass flowmeter/density meter is fixed to an inlet end and an outlet end of the measuring tube (11), thus clamping the same so as to allow the measuring tub e (11) to vibrate. The measuring tube (11) is made to vibrate mechanically, particularly to perform bending vibrations, by means of an excitation system (13). The inventive Coriolis mass flowmeter/density meter further comprises means (141, 142) for generating test signals (xs1, xs2 ) representing vibrations at the inlet end and outlet end of the measuring tube (11). An electronic evaluation unit (2) generates an intermediate value (X'm) that is derived from the test signals (xs1, xs2) and represents a tentatively determined mass flow rate as well as a second intermediate value (X2) derive d from the test signals (xs1, xs2), especially from a measured value (X.rho.) which is also generated in the electronic evaluation unit (2) and represents a density of the medium, said second intermediate value (X2) representing a measure of a concentration of a phase in the medium. A corrected value (XK) for the first intermediate value (X'm) is determined using the second intermediate value (X2), said corrected value (XK ) being selected among a plurality of predefined values stored in a table memory (56) by means of the intermediate value (X2). The electronic evaluation unit (2) additionally generates a measured value (Xm) representing a mass flow rate with the aid o f the intermediate value (X'm) and the corrected value (XK).

摘要： A measurement pickup, or transducer, includes at least one measuring tube for the conveying of a fluid. The measuring tube has an inlet end and an outlet end and vibrates at least at times. For enabling the fluid to be measured to flow through the measuring tube, the measuring tube communicates, via a first tube segment opening into the inlet end and via a second tube segment opening into the outlet end, with a pipeline connected therewith. For the oscillatable holding of the measuring tube, the measurement pickup further includes a support element having a first end piece containing a passageway for the securement of the first tube segment and having a second end piece containing a passageway for the securement of the second tube segment. Each of the two tube segments extends through its respective one of the two passageways and each of the two passageways has an inner diameter, which is greater than an outer diameter of its associated tube segment, so that an intermediate space is formed between each of the associated tube segments and end pieces. The measurement pickup further includes at least one, preferably metal, first spring element pushed onto one of the two tube segments. The spring element fills the intermediate space formed between tube segment and end piece at least partially, with the spring element being arranged in the intermediate space in such a manner that it contacts, at least sectionally, both its associated tube segment and also its associated end piece in such a manner that it is subjected, at least sectionally, to radially acting, deformation forces. As a result of elastic deformations accompanying such deformation forces, the spring element is held pressed against the associated tube segment and the associated end piece, whereby such tube segment is locked securely in the associated passageway.

摘要： Process control meter probe has a sensor arrangement that comprises a first sensor for measuring a primary measurement value and at least a second sensor for monitoring temperature within the temperature probe. The output of the temperature sensor is used by meter electronics to compensate the primary measurement value for temperature fluctuation, by application of a correction value. The correction value is based on the temporal behavior of the temperature measurement signal so that previous temperature values are considered.

摘要： Fluid mass flow rate transducer of the vibration type has a measurement pipe (10) with a predefined vibration frequency through which the measurement fluid is guided. The measurement pipe has an inlet (11) and outlet (12) pipes with which it is connected to the pipeline for which the mass flow rate is to be measured. An excitation arrangement (40) is provided to excite vibration of the measurement pipe including torsional vibrations. Said torsional vibration generate shear forces in the liquid. A vibration sensor (50) is provided as is a torsion vibration damper (60).

摘要： This mass flow sensor is to be fitted with two straight tubes, but conventionally needed manifolds are to be dispensed with. The sensor can be installed, by flanges, in a conduit of a given diameter so as to be axially aligned with the conduit, through which flows a fluid to be measured. It has a straight measuring tube, which extends between the flanges and is traversed by the fluid, and a straight dummy tube, which extends parallel to the measuring tube and is not traversed by the fluid. Also provided are a nodal plate on the inlet side and a nodal plate on the outlet side, one of which fixes the inlet-side end portion of the measuring tube to the corresponding end portion of the dummy tube, and the other of which fixes the outlet-side end portion of the measuring tube to the corresponding end portion of the dummy tube, such that the measuring tube and the dummy tube are arranged side by side. A support tube has its ends fixed to the respective flanges. A circuit for exciting resonance vibrations of the measuring tube acts only on the dummy tube. The measuring tube and dummy tube may also be coaxial with one another.
