摘要： A measurement processing system is disclosed for fusing measurement data from a set of independent self-validating (SEVA) process sensors (20) monitoring the same real-time measurand in order to generate a combined best estimate for the value, uncertainty and measurement status of the measurand. The system also provides consistency checking between the measurements. The measurement processing system includes a first process sensor (20) and a second process sensor (20).

A measurement fusion block (22) is connected to the first and second process sensors (20), the measurement fusion block (22) is operable to receive the independent process metrics and execute a measurement analysis process to analyse the independent process metrics and generate the combined best estimate of the independent process metrics.

摘要： Techniques are described for producing a signal (120) having a desired frequency. The desired frequency can be produced to a very high precision, even when the desired frequency is very high. The techniques, in one example, represent an intermediate, otherwise non-available frequency, by dithering between two exact frequencies (116, 118). Then, over some reasonably short timescale, the desired frequency is provided to high precision. Such precise frequency output may be used for, for example, measurement transmission and other uses. The techniques can be implemented in low-cost hardware, and may provide a precision of, for example, 10 -6 % for many frequencies.

摘要： Drive techniques for a digital flowmeter are described. The drive techniques account for delays caused during digital signal processing of sensor signals that correspond to a motion of a flowtube, as well as drive signals that impart motion to the flowtube. Such delays may be caused by a variety of factors, including delays associated with analog/digital conversion of the signals and/or filtering of the signals. The techniques include open-loop techniques and closed-loop techniques, which can be used separately or together during the start-up and operation of the digital flowmeter. Startup and operational techniques for a digital flowmeter also are described. The startup and operational techniques select an optimal mode of operation for the digital flowmeter, depending on a current environment of the flowmeter, where the mode of operation might be chosen from, for example, a random sequence mode, a positive feedback mode, or a digital synthesis mode. In either the positive feedback mode or the digital synthesis mode, the digital flowmeter may revert to a previous mode to regain stable and desired oscillation of the flowtube, such as might be required during a recovery operation associated with a disturbance to an operation of the digital flowmeter.

摘要： Motion is induced in a conduit such that the conduit vibrates in a major mode of vibration having a major amplitude and a minor mode of vibration having a minor amplitude. The major amplitude is larger than the minor amplitude, the major mode of vibration has a first frequency of vibration and the minor mode of vibration has a second frequency of vibration, and the minor mode of vibration interferes with the major mode of vibration to cause a beat signal having a frequency related to the first frequency of vibration and the second frequency of vibration. The frequency of the beat signal is determined, and the second frequency of vibration is determined based on the determined frequency of the beat signal.

摘要： Flowmeters are described in which a sensor signal received from a sensor that is attached to vibratable flowtube, so as to determine properties of a fluid within the flowtube, contains a drive signal component and a coriolis mode component. The flowmeters are operable to determine drive parameters of the drive signal component, as well as coriolis parameters of the coriolis mode component. By analyzing the sensor signal based on the drive signal parameters, and not on the coriolis signal parameters, the flowmeters are able to provide stable and accurate determinations of the properties of the fluid.
