Parameters (HART)

4.2.4.3: Level damping (F = 1 s)

Damping of level in s

Set the damping of the level value in seconds. It acts on the analog output, the limit value

monitor and the local display. For damping of the sensor signal, set Parameter 4.2.3.1.

4.2.4.4: MinLim Level (F = 0 m)

Lower limit value of the level (see Functional Dimensions on page 33)

Set the lower limit value of the level as a height above the LRV.

4.2.4.5: MaxLim Level (F = 20 m)

Upper limit value of the level (see Functional Dimensions on page 33)

Set the upper limit value of the level as a height above the LRV.

4.2.4.6: HYST Level (F = 0.5 m)

Hysteresis of the level limit values

Set the hysteresis of the limit values in the units system selected according to Parameter

4.1.1 (see diagram below).
