Model Number: VFD-2-#0293 Brand Name: VFD Anti-vibration Vortex Flowmeter Key Specifications/Special Features: Features:Advanced FFT spectral analysis signal processing technologyThe most advanced FFT technology in the world isadopted at present for analysis and processing of vortex flow signal and can accurately detect vortex information in low flow area, largely expand the measurable range of the flowmeterHigh stability and vibration resistanceAdopt international advanced dual-probe sensor technology, with one probe detecting fluid flow information and the other detecting pipe vibration information. When the pipe vibration intensity reaches 3g, the flowmeter can still accurately detect effective vortex information and realize accurate measurement, reflecting high stability and strong vibration resistanceHigh reliability: The power supply is adopted with reverse protection and purification treatment technologies, and vortex signal processing is adopted with isolation technology; thus, it has strong anti-EMI capacityLow flow: The lowest flow velocity that can be measured by theflowmeter is 0.2m/s. (temperature: 20 ; water density: 1000kg/m3)Wide range: Measurable range of flow is up to 1:20.VFD anti-vibration vortex flowmeterseries:
