P884 Peak Percentage
This parameter is used if you choose a solids application, P102 (Material) = 2
(Solids), where there may be angles of repose on the material. It can be used to
choose the point at which the measurement is taken within the returned echo.
The light blue line in the middle of the gate is the measurement point for the
unit. For liquid applications this occurs on the most vertical part of the leading
edge as the surface is generally quite flat giving an accurate measurement. For
solids applications the blue line appears in the centre of the echo as this is the
average point for a sloping surface, accuracy can vary on a sloping surface
depending on the ‘angle of repose’ of the material being measured.
Blue line on leading edge of echo for liquid
applications, but will move to centre of echo
for solid applications.
