WHAT IS A BAD ECHOCURVE?
Multiple peaks before or after the liquid or solids level
•
o If there are multiple peaks, the EchoBeam
trouble identifying which is the correct peak (liquid or
solids level).
o Performing a False EchoCurve will allow the
EchoBeam
o Also consider activating the Multiwave filter which can
be found under Configuration > Advanced > Settings
> Level Variables.
Change variable from NO to YES.
§
Peak underneath the orange line
•
o If the most significant peak is beneath the orange line
(Threshold Filter), then the return signal is weak.
o Consider changing the first Echo filter, which can be
found under Configuration > Advanced > Settings >
Signal Properties.
Change variable from the default of Normal to Big,
§
Bigger or Biggest.
Big will increase the peak by -10dB, Bigger by -
§
20dB and Biggest by -40dB.
o Performing a False EchoCurve will also allow the EchoBeam
it easier to identify the actual liquid or solids level.
Peak way above the orange line
•
o If the most significant peak is way above the orange
line (Threshold Filter), then the return signal is strong
and could affect the accuracy when the level is close
to full.
o Consider changing the first Echo filter, which can be
found under Configuration > Advanced > Settings >
Signal Properties.
Change variable from the default of Normal to

Small which will decrease the peak by -10dB.
