Vortex flowmeter using digital signsl processing techniques(DSP), design of 14 level digital bandpass filter, thought the rapid Fu liye software algorith, improves the vortex signal detection sensitivity, strengthen the vortex 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 signal effect pretreatment. Finally, the software uses the DSP technology, to achieve 14 band adaptive band-pass filter algorithm. This type of vortex converter using potentionmeter design, All debuggin using keys set, therefore, is convenient for field debuggin work,also improve the reliability of instrument.
Deals in manufacturing and supplying differential pressure gauges differential pressure gauge, precision engineered differential pressure transmitters, liquid differential pressure transmitters and differential pressure transmitters.
