Abstract: A measuring device electronics comprises a processor and two clock signal generators. One clock signal generator serves for producing a working clock signal, and also for producing a reference clock signal which is dependant on the working clock signal. The other clock signal generator, serves for producing a second reference clock signal, which is independent of the working clock signal. Based on the two independent reference clock signals, a frequency difference, can, to the extent that such is present, be ascertained during operation of the measuring device electronics or of the measuring device formed therewith. The frequency difference, represents a difference between the instantaneous clocking frequency of the first reference clock signal and the instantaneous clocking frequency of the second reference clock signal, and, in this respect, represents a measure for a deviation of an instantaneous clocking frequency, from the nominally predetermined clocking frequency, of the working clock signal.

Abstract: In a method for determining mass flow with a Coriolis mass flow measuring device arranged on a rotary filler, a correction value ?{dot over (m)} is ascertained, which is proportional to the RPM n of the rotary filler. This correction value is subtracted from the conventionally ascertained value {dot over (m)} of the mass flow. The corrected measured value {dot over (m)}corr is thus {dot over (m)}corr={dot over (m)}??{dot over (m)}.

Abstract: To ascertain the mass-flow of a Coriolis mass-flow meter, an oscillation of a measuring tube is produced with the frequency f and the resulting oscillatory movement is registered at two different measuring points with two oscillation sensors. The analog sensor signals X17, X18 of the two oscillation sensors are converted into digital sensor signals S1 and S2 and further processed in a digital signal processor DSP. In the signal processor DSP, the sum signal ? and the difference signal ? are formed from the two sensor signals S1 and S2. Then the sum signal is rotated by 90°. In a further method step, the shifted sum signal is multiplied with the difference signal ?. After ascertaining the amplitude of the sum signal ?, the mass-flow is ascertained using the formula {dot over (m)}˜|Im(?)|/(|?|f). It is not necessary for the method, that the two sensor signals S1, S2 have equal amplitudes. Thus, a controlling of the analog signals X17, X18 to equal amplitudes can be omitted.

Abstract: The viscometer comprises a vibratory transducer with at least one flow tube for conducting a fluid to be measured and for producing friction forces acting in the fluid. To vibrate the at least one flow tube, an excitation assembly is provided, which in operation is traversed by an excitation current. To generate the excitation current and a viscosity value representing the viscosity of the fluid, the viscometer includes meter electronics which are connected to, and supplied with electric power from, a two-wire process control loop. The meter electronics feed a viscosity signal corresponding to the measured viscosity value into the two-wire process control loop. The viscometer is suitable for measuring a fluid flowing in a pipe, particularly in potentially explosive atmospheres.
