What to do if Endress+Hauser Radar measured value jumps sporadically to a higher level?
- J
  Jeremy MillerAug 27, 2025
  If the measured value jumps sporadically to a higher level when the surface is not calm (e.g., during filling, emptying, or when an agitator is running) with your Endress+Hauser Radar, it's likely because the signal is weakened by the rough surface, making interference echoes stronger. Here are some steps to take: * Carry out tank mapping. * Select 'Process vessel with agitator' for the Tank type. * Increase the integration time. * Optimize the antenna orientation. * Select a better mounting position and/or larger antenna if necessary.

Why there is no change of measured value on filling / emptying with Endress+Hauser Radar?
- S

  If there's no change in the measured value during filling or emptying with your Endress+Hauser Radar, it's likely due to: * Interference echo from installations, nozzle, or build-up on the antenna. To resolve this: * Carry out tank mapping. * Clean the antenna if necessary. * Select a better mounting position if needed.

What to do if Endress+Hauser Micropilot FMR51 measured value is incorrect?
- B
  bellalexanderAug 25, 2025
  If the measured value of your Endress+Hauser Radar is incorrect, here are a few things you can check: * If the measured distance matches the real distance, there may be a calibration error. Check and adjust the Empty calibration parameter, Full calibration parameter and linearization if necessary. * For measurements in bypasses or stilling well, ensure the correct tank type is selected and the tube diameter parameter is correct. Select 'Bypass / pipe' for the tank type and enter the correct diameter in the Tube diameter parameter. * Enter the correct value in the Level correction parameter. * If the measured distance does not match the real distance, there may be an interference echo. Carry out tank mapping.
