12.5 Treatment of measurement errors

Fault description

Cause

Rectification

Amplitude or position of a

false signal has changed (e.g.

condensation, buildup); auto

false echo suppression no longer

matches actual conditions

Determine the reason for the

changed false signals, carry out

auto false echo suppression, e.g.

with condensation.

Fault description

Cause

Rectification

Measured value remains

unchanged during filling

False signals in the close range too

big or level echo too small
Strong foam or vortex generation
Max. adjustment not correct

Eliminate false signals in the close

range
Check measuring point: Antenna

should protrude out of the threaded

mounting nozzle, possible false

echoes through flange nozzle?
Remove contamination on the

antenna
In case of interferences due to

installations in the close range,

change polarisation direction
Create a new auto false echo

suppression
Adapt max. adjustment

Measured value jumps

towards 0 % during filling

The level echo cannot be

distinguished from the false signal

at a false signal position (jumps to

multiple echo)

In case of interferences due to

installations in the close range:

Change polarisation direction
Chose a more suitable installation

position

Measured value jumps

towards 100 % during

filling

Due to strong turbulence and

foam generation during filling, the

amplitude of the level echo sinks.

Measured value jumps to false

signal

Carry out a auto false echo

suppression

Measured value jumps

sporadically to 100 %

during filling

Varying condensation or

contamination on the antenna

Carry out a auto false echo

suppression or increase auto

false echo suppression with

condensation/contamination in the

close range by editing
