Yokogawa digitalYEWFLO Vortex Flowmeters
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 |
