ECHO CURVE

This function displays the primary echo return(s) that the sensor is seeing graphically as well as the location
and amplitude of the return(s). It can be used to confirm the correct level reading by the sensor or to
troubleshoot any false signals. There is a two step process involving the creating and viewing of an echo
curve. Note: Always consult a Flowline
#1 - CREATE AN ECHO CURVE

Note: LG10/LG11 series can store up to a total of three empty signal scans
and/or echo curve. Example: If an empty signal scan is active, EchoWave
will only store two echo curves. If an empty signal scan is not active, three
echo curves can be stores. Echo curves follow a first in first out logic.
#2 - VIEWING THE ECHO CURVE
The echo curve(s) scan can be viewed with the WebCal
