Treatment of measurement errors

The tables below give typical examples of application-related meas-
urement errors.
The images in column " Error description" show the actual level as a 
dashed line and the output level as a solid line.

Level

0

1  Real level
2  Level displayed by the sensor

Note:

If the output level is constant, the cause could also be the fault set-
ting of the current output to " Hold value". 
If the level is too low, the reason could be a line resistance that is 

too high

Liquids: Measurement error at constant level

Fault description

Cause

Rectification

Measured value shows a too 
low or too high level

Min./max. adjustment not correct

Adapt min./max. adjustment

Incorrect linearization curve

Measured value jumps to-
wards 100 %

Level

time

Due to the process, the amplitude of 
the level echo sinks
A false signal suppression was not car-
ried out

Carry out a false signal suppression

Amplitude or position of a false signal 
has changed (e.g. condensation, build-
up); false signal suppression no longer 
matches actual conditions

Determine the reason for the changed 
false signals, carry out false signal 
suppression, e.g. with condensation.
