Echo Profile
Press Enter to
- Review all Echoes
- Run a new Echo Rejection Profile
- Review an existing Echo Rejection
Profile
1.) Echo List Mode- Choose to review echoes in
Distance or Level
2.) Review all echoes using UP/DOWN arrows; listed in
descending Level value
3.) To run a new Echo Rejection Profile
a.) Choose the echo that corresponds to the actual
liquid level
b.) Press ENTER and confirm a new Echo Rejection
profile should be run. If necessary, Press ESCAPE
to exit at any time.
NOTES:
- ECHO REJECTION should run with vessel at or near
empty when all targets are exposed
- Re-run this routine if intial calibration is done with
significant liquid in vessel
- The Echo Rejection profile will be disabled and this
routine must be re-run if the following parameters
are modified: SENSOR OFFSET, TANK HEIGHT,
BLOCKING DISTANCE, DIELECTRIC,
TURBULENCE, FOAM
- The EchoRej Invalid message will be displayed if this
algorithm is DISABLED due to a parameter change.
4.) Enter Level- use this entry to manually enter the
correct level value
Error messages:
“Echo too Close”
indicates the liquid is too close to the
antenna. Liquid should not be closer than 30" (750
mm).
“Echo too Strong”
indicates an echo being rejected
is too strong.
a.) Ensure it is not the actual liquid level
b.) Rotate the Launcher to minimize the echo
5.) Saved Echo Rejection Profile-
a.) Enable or Disable an existing profile
b.) Review Echoes from an existing profile
c.) Review Level value where existing profile was run
