Buildup Detection
A unique feature contained within the Model 700 can be
used to obtain an indication of buildup along the length of
the probe. This can be set as the HART SV or TV which
can be monitored in the control room. An algorithm com-
pares the buildup echo strength as compared to the Lvl
Thrsh Value, and outputs value in percent.
