What to do if Rosemount Measuring Instruments show incorrect level reading?
- S
  Steven IngramAug 18, 2025
  An incorrect level reading on your Rosemount Measuring Instruments may be due to a configuration error. Check the Tank Height parameter in RRM>Setup>Tank. It could also be due to disturbing objects in the tank; ensure the transmitter hasn't locked onto an interfering object. You can also check status and diagnostics information.
