Siemens SITRANS LR500 Series - Lower Level Point Setting; Upper Level Point Setting; Sensor Offset Adjustment; Low-Level Cutoff Parameter

9.2.3.3 Lower level point (2.3.3)
Sets level value when material is at lower calibration point.
Setting -99999 to 99999 m
Default 0.0 m
9.2.3.4 Upper level point (2.3.4)
Se
ts level value when material is at upper calibration point.
Setting -99999 to 99999 m
Default 30 m
9.2.3.5 Sensor o󹪜se
t (2.3.5)
Sets o󹪜set to compensate for changes in sensor reference point.
Changes to sensor reference point may result from adding a thicker gasket or reducing the
stando󹪜/nozzle height.
Setting -99.999 to 99.999 m
Default 0
If amount of parameter "Sensor o󹪜set" is known, enter the constant that can be added to or
subtracted from sensor value
1)
to compensate if the sensor reference point has shifted.
1)
The value produced by the echo processing which represents the distance from sensor
reference point to the target
9.2.3.6 Low-level cuto󹪜 (2.3.6)
Sets lower limit on measured value (before any o󹪜set applied).
For example, set value to zero to prevent a negative level measurement.
Setting -999 to 0.0
Default 0.0
Note
Def
ault value disables parameter
By using the default value of -999, or a lower value, the parameter "Low-level cuto󹪜" is disabled.
9.2.3.7 Propagation factor (2.3.7)
Se
ts value that represents reduction in propagation velocity as a result of the wave travelling
through a pipe.
