Registration of False Echoes
The False Echo function allows you to let the transmitter register
disturbing echoes caused by objects in the tank. This makes it
possible to detect a product surface close to a disturbance echo
even if the surface echo is weaker than the disturbing echo.
1 Select the False Echo tab
2 Click the Read button to update the list of interfering echoes.
The right-hand list displays disturbances that was detected by the
transmitter. In order to optimize the measurement performance, you
may need to register interfering echoes as described below.
Note! Registration of disturbing echoes requires that Saab´s echofixer is
enabled.
When should I register?
See the following recommendations before you register new interfering
echoes:
• Make sure that a correct amplitude threshold is set before you
register any disturbance echoes. See description of the Spectra-
Threshold window
• Keep the number of registered echoes to a minimum.
• Compare the list of interfering echoes with the tank drawing or by
visible inspection of the tank. Note if there are objects like beams,
heating coils, agitators etc. which correspond to the found echoes.
Only register echoes which can be clearly identified as objects in
the tank.
