Anatomy of an Echo Trace

  • Echo Trace– Signal returned to the transducer mapping the application.
  • Echo Marker– Echo that the software is analyzing as the level to be measured.
  • Gate– Set distance either side of the echo marker which is the ‘normal’ area that an echo will change within.
  • Near Blanking– Distance from the transducer face in which no echo signal can be recorded.
  • Far Blanking– Distance further than the measurement range of the transducer.
  • Loss Limit– Threshold that indicates the echoes to be ignored because they are below this line.
  • Datum line– Indicates the noise threshold calculated e.g. the base echo line.
  • Empty level – The maximum distance that can be measured if the application (e.g. tank, wet well) was empty
