Why is the measured value incorrect on my Endress+Hauser Radar?
- D
  David WardSep 8, 2025
  If the measured value on your Endress+Hauser Radar is incorrect, check and adjust the Empty calibration parameter and the Full calibration parameter. If necessary, check and adjust linearization. For measurements in bypasses or stilling wells, select the correct Tank type (Bypass / pipe) and enter the correct diameter in the Tube diameter parameter. You may also need to enter the correct value in the Level correction parameter.

Why does Endress+Hauser Micropilot FMR51 display a level when the tank is empty?
- S
  snavarroSep 7, 2025
  If the Endress+Hauser Radar displays a level when the tank is empty, it's likely due to an interference echo. Perform a mapping over the entire measuring range when the tank is empty by using the Confirm distance parameter.

Why during filling/emptying the measured value jumps downwards on Endress+Hauser Micropilot FMR51?
- J
  Jenna FowlerSep 1, 2025
  If, during filling or emptying, the measured value jumps downwards on your Endress+Hauser Radar, it could be caused by multiple echoes. To address this: * Check the Tank type parameter. * If possible, avoid a central installation position. * If appropriate, consider using a stilling well.

How to fix error message F941 or S941 "Echo lost" on Endress+Hauser Micropilot FMR51 Radar?
- K
  Kathy BennettAug 27, 2025
  The error message F941 or S941 "Echo lost" on your Endress+Hauser Radar indicates that the level echo is too weak or suppressed. To resolve this: * Check the Medium group parameter. If necessary, select a more detailed setting in the Medium property parameter. * Optimize the alignment of the antenna. If necessary, select a better installation position and/or larger antenna. * If the level echo is suppressed, delete the mapping and record it again.
