System
Todetectoverow,anoverow
sensor is much more accurate
than a threshold from the level
sensor.Bysettingparameters
(exponentsandconstants)the
overowcanalsobeaccurately
measuredbyacalculation.‘Lock
oninow’simplyusesthehis-
toricalvalueofinow.
Level Limit is the level at which
overowisexpected.Note:not
