摘要： The density measuring device serves for measuring density, ρ, of a flowable medium and comprises a measuring device electronics (ME) as well as a measuring transducer (MT) electrically connected therewith. The measuring transducer includes a measuring tube (10), an oscillation exciter (41) for exciting and maintaining oscillations and an oscillation sensor (51) for registering oscillations of the at least one measuring tube. The measuring device electronics is adapted by means of an oscillation measurement signal (s1) as well as an exciter signal (e1) to adjust a drive force effecting wanted oscillations (namely oscillations with a predetermined wanted frequency, fN) of the measuring tube. The drive force is adjusted in such a manner that during a predetermined phase control interval a phase shift angle, φN, by which a velocity response, VN, of the measuring tube Is phase shifted relative to a wanted force component, FN, of the drive force, is less than −20° and greater than −80°, and/or the wanted frequency has a frequency value, which corresponds to greater than 1.00001 times, equally as well less than 1.001 times, a frequency value of an instantaneous resonant frequency of the measuring tube. Moreover, the measuring device electronics is adapted based on the oscillation measurement signal (s1) present during the phase control interval to ascertain at least one frequency measured value, Xf, which represents the wanted frequency for the phase control interval, as well as also with application of the frequency measured value, Xf, to generate a density measured value, Xρ, representing a density, ρ.

摘要： A Coriolis mass flow measuring device comprises a measuring device electronics as well as, connected thereto, a measuring transducer comprising at least one measuring tube, an oscillation exciter for oscillating the at least one measuring tube and, mutually spaced along the measuring tube, two oscillation sensors for generating oscillation signals representing oscillations of the measuring tube. The measuring tube is adapted to be flowed through by a medium and during that to be caused to vibrate in such a manner that the measuring tube executes wanted oscillations having a wanted frequency. The wanted oscillations are suitable to induce in the flowing medium, dependent on its mass flow rate, Coriolis forces suitable for bringing about a measurement effect of a first type, namely Coriolis oscillations of the wanted frequency superimposed on the wanted oscillations. These Coriolis oscillations are, in turn, suitable to induce in the medium centrifugal forces dependent on its mass flow rate and on its density. These centrifugal forces bring about a measurement effect of a second type, namely, superimposed on the Coriolis oscillations, centrifugal oscillations of the wanted frequency. The measuring device electronics is, among other things, adapted, based on the oscillation signals, to generate at least one mass flow, measured value, representing the mass flow rate, in such a manner that a dependence of a phase difference existing between wanted signal components of the oscillation signals is taken into consideration by the measurement effect of second type.

摘要： A method for determining a viscosity of a medium based on damping of an oscillation mode of a measurement tube comprises exciting oscillations of an oscillation mode; detecting a sequence of provisional damping measurement values for the measurement tube oscillation mode; and calculating target measurement values. The influence of the cross-sensitivity of the damping for the flow rate of the medium is corrected by determining rectified damping measurement values that correspond to damping when the medium is at rest and determining viscosity on the basis of the rectified damping measurement values, or correcting the influence of the cross-sensitivity of the damping for the flow rate of the medium by determining provisional intermediate values of a damping-dependent variable, determining rectified intermediate values that correspond to the intermediate values when the medium is at rest, and determining the target measurement values on the basis of the rectified intermediate values.
