Yokogawa digital YEWFLO vortex flowmeter



Yokogawa digitalYEWFLO vortex flowmeter
The new digitalYEWFLO vortex flowmeter is the latest offering in our line of world class vortex flowmeters. Based on the field-proven sensor technology of the YEWFLO series of vortex flowmeters, digitalYEWFLO offers a unique signal processing technique that extends the features of DSP. 
The advanced processing algorithms are known as Spectral Signal Processing (SSP). SSP analyzes the vortex waveform into its spectral components to filter noise from signal for the most stable measurement possible.

General Specifications


Features: digitalYEWFLO Vortex Flowmeter

New functions with Spectral Signal Processing (SSP) technology
  SSP analyses the fluid conditions inside the digitalYEWFLO vortex flowmeter and uses the data to automatically select the optimum adjustment for the application, providing features never seen before in a vortex flowmeter.
SSP accurately senses vortices in the low flow range, providing outstanding flow stability.
Advanced self-diagnostics
  Application conditions such as high pipeline vibration and abnormal flow are predicted and indicated.
High accuracy
  ±0.75% of reading (liquid)
±1.0% of reading (gas, steam)
Wide process temperature range
  High temperature version up to 450 deg C
Cryogenic version minimum -196 deg C
Simple parameter settings
  Frequently-used selections grouped together in a quick-access format decrease commissioning time
Clear, concise indicator
  Convenient display of the simultaneous and total flow rates together with the process diagnosis
Dual output for analog/pulse
  Simultaneous output for flow rate and pulse
Alarm output
  An alarm signal is output when an alarm occurs.
BRAIN/HART communication and key switches for human-machine interface
NACE compliant
NAMUR 43 compliant
Remote cable length up to 30m
