FLOWSIC100 PR-EX-Z2
|
|
| |
Volume Flow Measurement for Process Applications Easy installation - wide measuring range - reliable and precise measurement With the device type FLOWSIC100 PR-EX-Z2 measurements can be carried out with ambient pressures up to 0.1 bar (1.45 PSI). Therefor materials of hermetically sealed stainless steel or titanium are available. The installation is carried out from one side only.
This device is constructed as Ex-protected version for use in hazardous area zone 2 according to ATEX guideline 94/9/EC (version for zone 1 on request). |
