What to do if level reading on Magnetrol Enhanced Model 705 is stuck at full scale?
- J
  jeremytorresAug 21, 2025
  If the level reading on the Magnetrol Transmitter display is stuck at full scale, it could be because the software thinks the probe is flooded, meaning the level is very near the top. First, check the actual level. If the probe isn't flooded, inspect for buildup or obstructions near the top. You might also select a higher dielectric range, check for condensation in the probe connection, or add blocking distance.

What causes fluctuating LEVEL and AI OUTPUT values due to probe coating on Magnetrol Enhanced Model 705 Transmitter?
- E
  Elizabeth NelsonSep 3, 2025
  If the LEVEL and AI OUTPUT values from your Magnetrol Transmitter are fluctuating, it could be due to coating, clumping, or buildup on the probe. These inaccuracies may be expected due to their effect on pulse propagation.

Why is LEVEL value reading high when it should be zero on Magnetrol Transmitter?
- B
  Benjamin OrtizSep 1, 2025
  If the LEVEL value on your Magnetrol Transmitter is reading high when it should be zero, the transmitter may be loose or disconnected from the probe. Ensure the transmitter is securely connected to the probe.

How to correct repeatable but inaccurate LEVEL readings on Magnetrol Transmitter?
- B
  Barbara RobertsAug 31, 2025
  If the LEVEL readings on your Magnetrol Transmitter are repeatable but consistently high or low by a fixed amount, the configuration data may not accurately match the probe length or tank height. Ensure the proper Probe Model and probe length are set. Adjust the trim level value by the amount of the noted inaccuracy.

Why are LEVEL and AI OUTPUT values at maximum level on Magnetrol Transmitter?
- A
  Anthony RiveraAug 29, 2025
  If the LEVEL and AI OUTPUT values from your Magnetrol Transmitter are all at the maximum level, there may be a configuration issue. For a single rod probe, increase the Blocking Distance. You can also try increasing the Dielectric Range.

Why are LEVEL and AI OUTPUT values reading low on Magnetrol Enhanced Model 705 Transmitter?
- P
  Patricia JohnsonAug 27, 2025
  If the LEVEL and AI OUTPUT values from your Magnetrol Transmitter are all reading low compared to the actual level, it could be due to a lower dielectric material being over a higher dielectric material, such as oil over water. In this case, select the Fixed Threshold option.

What causes high LEVEL and AI OUTPUT readings on Magnetrol Enhanced Model 705 Transmitter?
- M
  Mason MuellerAug 26, 2025
  If the LEVEL and AI OUTPUT values from your Magnetrol Transmitter are reading high compared to the actual level, there might be an obstruction in the tank affecting the single rod probe. To resolve this, you can increase the Dielectric Range until the obstruction is ignored or relocate the probe away from the obstruction.

Why do LEVEL and AI OUTPUT values fluctuate on Magnetrol Enhanced Model 705 Transmitter?
- E
  Eric ThomasAug 26, 2025
  If the LEVEL and AI OUTPUT values from your Magnetrol Transmitter are fluctuating, it may be due to turbulence. To stabilize the readings, increase the AI Block process value filter time.

How to fix inaccurate LEVEL and AI OUTPUT values on Magnetrol Transmitter?
- C
  cindybrownAug 23, 2025
  If the LEVEL and AI OUTPUT values from your Magnetrol Transmitter are inaccurate, the basic configuration data might be questionable. Try reconfiguring the Probe Model, Probe Mount, Probe Length, or Level Offset. Also, ensure the level is accurate and verify the EU_0% and EU_100% values.
