Tracking data
- Level Tracking Function for moving the valid window from immediately prior liquid level
variation if valid echo detection could not be performed
(ON/OFF)
Fig. 6.6.10 Level tracking
- Level Prediction Function that outputs the liquid level predicted from the immediately
prior liquid level variation, if valid echo detection could not be
performed
(ON/OFF)
- Slow Search If this function is set to ON when valid echo detection could not be
performed for Re-search Delay, the valid window is enlarged, using as
reference the position where the immediately prior echo disappeared.
(ON/OFF)
- Slow Search-Speed Set the distance per second to enlarge the effective window during
slow search. The distance to be enlarged varies depending on the
search time. (0.0m to 99.999m)

- Empty Tank Detection Function that considers the liquid level to be zero if the level of the
immediately prior liquid surface echo is at or less than the empty
tank detection position, if valid echo detection could not be performed
(ON/OFF)
- Position Empty tank detection position (0.0m to 99.999m)
