Why does my Siemens Transmitter LR 460 read 100% continuously?
- J
  Jamie GordonAug 31, 2025
  If your Siemens Transmitter LR 460 consistently reads 100%, it could be due to a false echo near the antenna. Try moving the LR 460 to a better location, rotating it to change the polarization field, shortening the vessel nozzle to allow the antenna to project into the vessel, or aiming the LR 460 away from the false echo. Another cause could be antenna buildup. In this case, clean the antenna, install a PTFE dust cover, or use the Air Purge option.

Why does the PLC value equal the display value, but not correspond to actual material level on my Siemens sitrans lr 460 Transmitter?
- S
  Samuel PhillipsAug 30, 2025
  If the PLC value equals the display value but doesn't match the actual material level in your Siemens Transmitter, there might be incorrect scaling in AIFB. Try adjusting the scaling in AIFB. Alternatively, the High Calibration Point might be entered incorrectly; in that case, correct the High Calibration Point setting.
