Vortex flow meter using digital signal processing techniques(DSP), design of 14 level digital bandpass filter, the rapid Fu liye software algorithm, vibration resistance performance, breaks through the traditional simulation method for the vortex signal processing limitation. The SDVFM converter hardware used in the variable gain amplifier: to adapt to various caliber vortex sensor signal strength, the variable with of multilevel filter, the vortex signal effective pre-treatment. Finally, the software uses the SDP technology to achieve 14 band adaptive band-pass filter algorithm . The type of vortex converter using potentiometer design, all debugging using keys set, therefore is convenient for field debugging work, also improve the reliability of the instrument.
