If you do not know the resistance, select Compute from gauge and length and enter the wire gauge and wire length.
The procedure will present an estimate of your wire resistance along with the parameters used to compute it, and
offer you the choice of accepting the value or not. Accepting will use the computed wire resistance estimate in the
calculation of process temperature. Aborting the procedure will retain the previously configured value of wire
resistance.
D Fluids is visible in Interface Level only.
D Fluid is visible in Liquid Level only.
Upper Fluid Density
indicates the density of the upper process fluid when Primary Variable is Interface Level.
Lower Fluid Density
indicates the density of the lower process fluid when Primary Variable is Interface Level,
or
indicates the difference between densities of lower and upper process fluids when Primary Variable is Liquid Level.
View/Edit SG Tables allows you to review or edit the configuration of density temperature compensation for the
upper or lower fluid tables.
Example entries for saturated water are given in table 4‐2. Figure 4‐4 shows the curve that results when these values
are plotted.
