Algorithm Parameter (P820)
P820 Algorithm
(F = 8)
Selects the algorithm to be applied to the echo profile in order to extract the true echo.
Select 8 (bLF) for most applications and all mounting locations except the center of the
vessel. Select 12 (F) for the center of the vessel mounting location and for still pipes and
waveguide antennas used as stillpipes. Select 3 (L) only when the vessel level will remain
at low levels.
TVT (Time Varying Threshold) Adjustment Parameters
(P830 to P841)
The following parameters are for authorized Siemens Milltronics Service personnel or
technicians familiar with Siemens Milltronics echo processing techniques. Dolphin Plus
should be used to view the echo profile before attempting to modify these parameters.
