Why do Rosemount 3051SFC_A Measuring Instruments give a high reading?
- S
  Selena RobertsAug 12, 2025
  If your Rosemount Measuring Instruments are showing a high reading, here are a couple of things to check: * The Annubar sensor might not be installed in the proper pipe size. To resolve this, verify the actual pipe ID and wall dimensions and compare them to the Calculation Data Sheet. If the dimensions do not match, consult the factory. * The DP transmitter might not be zeroed or configured correctly. You should verify that the DP sensor has been zeroed properly, that the transmitter range is correct, and that the square root output is correct. Also, verify that the Annubar sensor calc sheet represents fluid density properly so that the transmitter is configured correctly for the application.

  If the Annubar sensor won't fit in the drilled hole for your Rosemount Measuring Instruments, here's what to investigate: * The drill hole might not be the proper size. Verify that the drill hole matches the size specified in the installation instructions. Re-drill the mounting hole with the proper drill hole size. * The drill hole might not be aligned properly with the Annubar sensor mounting hardware. Verify that the mounting hardware is centered over the pipe hole. If necessary, reinstall the mounting hardware. * The hole might have been torch-cut, leaving pipe fragments blocking the hole. Re-drill the hole in a different location as specified in the installation instructions.
