摘要： A vortex flowmeter for calculating the flow rate of a measuring fluid flowing through a flow path using ultrasonic signals subjected to changes in the propagation time due to Karman vortices, comprising a reference signal generating device for outputting a plurality of reference signals of different phases; a signal analyzing device for outputting an input status signal by determining the relationship between the phases of the ultrasonic signals and each reference signal; a plurality of phase detectors for outputting phase signals by detecting the phase difference between the ultrasonic signals and the reference signals; and a channel selector for selecting the optimum phase signal using the input status signal and for outputting the optimum phase signal as a selection signal, wherein the flow rate signals are computed and outputted using the selected phase signal. The vortices are thus stably detected even when a phase change due to the vortices in the vortex flowmeter is large.

摘要： First and second ΔΣ modulators convert output signals of two sensors into pulse density signals. First and second LPFs convert the pulse density signals into multi-bit signals. A signal computing module calculates a mass flow rate based on the multi-bit signals. A resonance circuit generates an excitation signal based on the output signals of the sensors. A drive output module amplifies the excitation signal. An exciter excites the measurement tube using an amplified excitation signal. A multiplier amplifies one of the pulse density signals to generate a multi-bit signal. An amplification factor controller controls an amplification factor of the multiplier based on the multi-bit signal. A third ΔΣ modulator converts an amplified signal into a pulse density signal. A DAC generates the excitation signal based on the pulse density signal.
