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 HydroRanger 200 is monitoring the vessel to avoid stationary blade
detection.
When set for max verification or material agitator, a new measurement outside of the
Echo Lock Window (P713) must meet the sampling criterion (P712).
For total lock, Echo Lock Window (P713) is preset to zero 0. The HydroRanger 200
continuously searches for the best echo according to the algorithm chosen (P820). 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 HydroRanger 200 responds immediately to a new
measurement as restricted by the Max Fill / Empty Rate (P700 / P701); however,
measurement reliability is affected.
