YOKOGAWA digitalYEWFLO High Process Temperature Version / Cryogenic Version Vortex Flowmeters
We have the process temperature version and cryogenic version in the digitalYEWFLO series which boast the long-term reliability.
The high process temperature version is available up to 450 degrees C, the highest temperature in the voｒtex flowmeter.
The cryogenic version is available up to -196 degrees C .
These versions are the best solutions for the high temperature steam application or the cryogenic liquid oxygen up to 200 mm of the nominal sizes.
Features: High Process Temperature Version / Cryogenic Version
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
