Flow meter

SDVFM vortex flowmeter using digital signal processing techniques (DSP), design of 14 level digital bandpass filter, thought the rapid Fu liye software algorith, improves the vortex signal detection sensivity, 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 sensor signal strength, the variable width of multilevel filter, the vortex signal effect pretreatment. Finally, the software uses the SDP technology, to achieve 14 band adaptive band-pass filter algorithm. This type of vortex converter using potentionmeter design, All debugging using keys set, therefore, is convenient for field debugging work, also improve the reliablity of the instruments.

An advance version of SDVFM Series Vortex Flow Meter have temperature & pressure compensation feature. Sensor which sense Fluid varying temperature & pressure & process these values & display the flow within accuracy limit therefor, change in temperature & pressure of fluid does not affect the performance of Vortex Flow Meter.
