Product Information
 |
||||||||||||||||||||||||||
| 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 |
