Operating Instructions
2.5 Roping compensation Roping compensation sub-menu
The stratification compensation is used to compensate for measurement uncertainties which can
arise due to stratification. The sensors are supplied with an optimum default setting for normal
conveying conditions. If the measurement is influenced by unusual flow stratifications or stratification
shifts, the intensity of the compensation can be increased from 0 % to up to 100 %.
The sensor has two parameter sets for gravimetric and pneumatic conveying conditions. They should
be selected depending on the type of conveyance. The intensity adds part of the compensated
measurement to the uncompensated measurement: Both parts are weighted and calculated
according to the selected intensity.
When using this function, we recommend only increasing the intensity in 10 % steps and to assess
the quality of the measurement results in each case.
A manual parameter set can be set and permanently stored by trained SWR personnel.
2.5.1 Conveyor
2.5.2 Intensity
Selection: AUS (OFF)/ GRV / PNE / MAN
Input: 0 ... 100 %
AUS (OFF): no compensation
GRV: gravimetric conveyance = free fall
PNE: Pneumatic conveyance
MAN: Manual parametrisation
(only for trained SWR personnel)
Strength of calculation of compensated
signal with the uncompensated signal, e. g.:
0 %: 0% compensated signal element,
100 % uncompensated signal component
10 % 10% of the compensated and 90 %
of the uncompensated signals are calculated
100 %: the output signal contains 100 %
of the compensated component
