摘要： 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.

摘要： 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.

摘要： Such an excitation circuit is intended for use in a Coriolis mass flowmeter which is connected to, is powered exclusively from, and outputs a measurement signal exclusively via, a two-wire process control loop. The Coriolis mass flowmeter has a vibrating flow tube and an excitation assembly for vibrating the flow tube at a frequency equal or adjacent to the instantaneous mechanical resonance frequency of the flow tube. It further comprises transducer assemblies which are positioned at a given distance from each other along the flow tube and provide respective transducer signals. The excitation circuit may comprise a peak detector to which one of the transducer signals is applied as an input signal, a comparsion stage which determines a deviation of the output signal of the peak detector from an adjustable reference signal that specifies an amplitude of the vibration of the flow tube, a multiplier for the input signal to the peak detector and the output signal from the comparsion stage, and an output stage having an input connected to an output of the multiplier and supplying the excitation assembly. Instead of the multiplier, a pulse duration modulator or a DC/DC converter and a comparator may be provided.

摘要： This Coriolis mass flow sensor (40, 50, 60, 70) can be inserted in a pipeline by means of an inlet-side and an outlet-side connecting element (402, 403; 502, 503; 602, 603; 702, 703). An oscillating system comprises at least one measuring tube (401; 501; 601; 701, 701'), through which a fluid to be measured flows in operation. The oscillations of the oscillating system are excited by means of an electromagnetic exciter arrangement (1, 2, 3, 4, 10) which has at least one low-resistance exciter coil (15; 251, 252; 35) fed from an exciter current source (6, 7), a core (13, 23, 33, 43, 53) containing a permanent magnet (12; 221, 222; 32; 42; 512, 522), and an armature (14, 24, 34, 44, 54, 104). The oscillating system can also be excited by interference vibrations which contain a frequency which is the same as the resonant frequency of the oscillating system, such that the measurement result is corrupted. To avoid this a capacitor is coupled to the coil in the manner of a parallel circuit and its capacitance (C) is selected as a function of the inductance (L) of the coil such that the resonant frequency of the electrical parallel resonant circuit which is formed by the capacitor and the coil is approximately equal to the mechanical resonant frequency of the oscillating system. A sensor (406, 506, 606, 706) for the inlet-side oscillations and a sensor (407, 507, 607, 707) for the outlet-side oscillations are arranged with the same distance between the center of the measuring tube and the inlet-side and the outlet-side connecting element, respectively.

摘要： The present Coriolis mass/flow density meter and method for measuring a mass flow rate of a medium flowing through a flow tube of a Coriolis mass flow meter provide measurement results which are independent of the current velocity field of the medium to be measured. At least one measuring tube is provided, through which the medium flows, which oscillates during operation. A means for measuring the oscillations is arranged at an inlet end of the measuring tube and provides a measurement signal. A second means for measuring the oscillations is arranged at the outlet of the measuring tube and provides a second measurement signal. A third measuring means provides a third measurement signal which represents the current Reynolds number of the flowing medium, Evaluation electronics generate a measurement value representing the mass through-flow. The evaluation electronics also generate a measurement value representing the current density of the medium.
