If a material agitator (mixer) is used in the vessel monitored, set Echo Lock for
Maximum
verification
or
Material agitator
to avoid agitator blade detection. Ensure the agitator is
always ON while the device is monitoring the vessel to avoid stationary blade detection.
When set for
Maximum verification
or
Material agitator
, a new measurement outside of the
Echo Lock Window (2.11.5.5.) (Page 235) must meet the Measurement Verification (2.11.5.)
(Page 233) criterion.
For, Echo Lock Window (2.11.5.5.) (Page 235
) is preset to zero (
0
). The device continuously
searches for the best echo according to the
Algorithm (2.11.2.2.) (Page 222) chosen. If the
selected echo is within the window, the window is then centered about the echo. If not, the
window widens with each successive shot until the selected echo is within the window. The
window then returns to its normal width.
When Echo Lock is OFF, the device responds immediately to a new measurement as
restricted by the Fill Rate/minute (2.3.2.) (Page 173) and Empty Rate/minute (2.3.3.)
(Page 173); however, measurement reliability is affected.
