ABSTRACT:
The present invention discloses an intelligent signal processor of a vortex flowmeter, the signal processor mainly adopts a digital signal processor structure for processing a flow rate of a fluid. The signal processor uses two different algorithms, one primarily using a fast Fourier transformation (FFT) unit and an auto-correlation unit, and the other primarily using a fast Fourier transformation (FFT) unit and a digital software phase locked loop (SPLL) unit. As the flow rate varies with time, the two algorithms can track a vortex shedding frequency and reduce a vortex shedding frequency error. For maximum and minimum flow rates, a large difference of flow rates will not affect the precision of a measurement. If the flow rate ranges from 50 to 509 m3/hr, the precision is approximately equal to 0.59%˜0.35%, which has improved about 2˜3 times over the traditional processing method.
