Parameters

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.

P712 Echo Lock Sampling

The sampling criterion sets the number of consecutive echoes appearing above or below

the echo currently locked onto, that must occur before the measurements are validated

as the new reading (for Echo Lock P711 values: 1 or 2).

Example:

Setting

• P711 = 2, material agitator

• P712 = 5:2

Result

• a new reading will not be validated unless five consecutive measurements higher or

two consecutive measurements lower than the current reading occur

• Resetting P711 returns P712 to the respective preset values
