Parameters (HART)
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).
Limit value alarm
4.2.5: Volume parameters
To calculate the volume of the measuring medium, you need the level parameters (see
parameter 4.2.4) in the units selected according to parameter 4.1.1 and additionally a
vessel characteristic (parameter 4.2.5.7).
