Measurement Support data
- Averaging Time Mean movement time for measurement value
(1sec to 120sec)
- Median Filter Number of excluding deviations in the measurement values within the
mean movement time.
(0sec to 120sec / Default: 0 sec)
Fig. 6.6.2 Median Filter
Fig. 6.6.2 indicates setting at “Average Time”5sec and “Median Filter”2sec.
KRG-10 will generate 1 measured result (process value) every 1 second.
5 sec means KRG-10 can generate 5 measured values.
In case that you will set 2 sec for Median Filter value, it means removing 2 values from 5
measured values to get median value by 3 measured values.
Number of measurement values – Median Filter time Calculated values
To get smooth value, Median Filter should be set as minimum.
On the contrary, Median Filter should be set as maximum to get vivid value such as rapid
level changing condition.
- Alarm Delay Time until alarm is output after data was missed
(1sec to 120sec)
- Re-search Delay Time until searching the liquid level echo after data was missed
(1sec to 120sec)
- Surface Detect Mode Echo detected as the liquid level echo
(Max Echo / first Echo)
