Why does the measured value sporadically drop to lower levels when filling the vessel with Endress+Hauser Prosonic S FMU90 Measuring Instruments?
If, when filling the vessel, the measured value sporadically drops to lower levels on your Endress+Hauser Measuring Instruments, change the "tank geometry" to "dome ceiling" or "horizontal cylinder".
What causes different units for calculation of average value, sum, difference or rake control in Endress+Hauser Measuring Instruments?
If you're seeing different units for calculating average value, sum, difference, or rake control on your Endress+Hauser Measuring Instruments, check the units of the respective basic calibrations in the "level" or "flow" menu.
What to do if current 01 or 02 is out of measuring range on Endress+Hauser Prosonic S FMU90?
If current 01 or 02 is out of the measuring range on your Endress+Hauser Measuring Instruments, perform a basic calibration and check linearisation.
What does 'linearisation points level 01 or 02: number < 2' mean on Endress+Hauser Prosonic S FMU90 Measuring Instruments?
This message on your Endress+Hauser Measuring Instruments indicates that you need to enter further linearisation points in the "level" menu.
