Add a new false echo suppression
Prerequisites
Follow these recommendations before suppressing new false echoes:
•
Make sure a correct amplitude threshold is set (see
).
•
Make sure the level is stable. A fluctuating level may indicate a temporary disturbance
which is not due to an interfering object.
•
Only suppress echoes which can be clearly identified as objects in the tank. Compare
the list of interfering echoes with the tank drawing or visual inspection of the tank.
•
Do not suppress false echoes located below the product surface.
•
Keep the number of suppressed false echoes to a minimum.
It may be necessary to suppress new false echoes at a later stage when objects have
become visible due to surface movement.
