Siemens SITRANS LR500 Series - Filtering Parameters

De󹪝nes wher
e on the echo the distance measurement is determined.
Setting Rising edge per‐
cent
age
Rising edge of echo (calculated using echo peak to echo 󹪞oor
percentage): Yields highest stability on solid materials
Center Calculated center of the echo peak: service only
Rising2 Service only
Center2 High accuracy center for 󹪞at t
argets
Default Center 2 Liquids, rising edge percentage for solids
Echo marker (3.3.3.4)
De󹪝nes t
he point of measurement on the echo.
Setting 5% to 95%
Default 75 (%)
Applicable only when using "Rising" algorithm, set in parameter "Position detect".
9.3.3.4
Filtering (3.3.4)
Reform echo (3.3.4.1)
Used to smooth jagged peaks in the echo pro󹪝le. Reforms fragmented echoes into one echo.
Setting 0 to 50 intervals (greater = wider)
Default 0 (o󹪜) liq
uids, 15 solids
Use this feature when monitoring solids if the reported level 󹪞uctuat
es slightly though the
monitored surface is still. Enter the amount of smoothing required to the echo pro󹪝le. When
a value is entered, the nearest acceptable interval value, in microseconds, is set.
Near range suppression (3.3.4.2)
Used to automatically suppress signal from sensor reference point to near range suppression
distance (0 = o󹪜).
Setting 0 to 255
Default 0
Note
If
Near range suppression is enabled, Auto false echo suppression (Page 98) must be disabled.
Near range suppression distance (3.3.4.3)
Se
ts distance for near range suppression.
