5.4.3 Temperature panel
The Temperature panel is shown in Figure 5-4. Parameters on this panel control how the sensor will
measure and report temperature data to the Model 3711. Parameters are listed and defined in
Table 5-3.
Table 5-2 Density configuration parameters
Parameter Description Comments
Damping Period The number of seconds over which the reported density value
will change to reflect 63% of the change in the actual process.
See Section 5.5.2. Default: 1.6 seconds
Low Density
Cutoff The density value below which the Model 3711 will report a
value of 0 for density. Default: 200 kg/m
3
(12.48 lb/ft
3
)
Range: 0–5000 kg/m
3
(312.14 lb/ft
3
)
Slug Duration The number of seconds the Model 3711 waits for a slug flow
condition (
outside the slug flow limits) to return to normal ( inside
the slug flow limits). See Section 5.5.4.
Default: 0.0 seconds
Range: 0.0–60.0 seconds
High Slug Limit The density value above which a condition of slug flow will exist.
Typically, this is the highest point in the normal density range of
the process. See Section 5.5.4. Default: 5.0 g/cm
3
Range: 0.0–10.0 g/cm
3
Use g/cm
3
to configure this
parameter, even if you have
configured U.S. units.
Low Slug Limit The density value below which a condition of slug flow will exist.
Typically, this is the lowest point in the normal density range of
the process. See Section 5.5.4. Default: 0.0 g/cm
3
Range: 0.0–10.0 g/cm
3
Use g/cm
3
to configure this
parameter, even if you have
configured U.S. units.
Density Meter
Factor The adjustment to be applied to the density process variable.
See Section 5.5.3. Default: 1.0
Flowing Density
Factor The correction factor for the effect of flow on density. Enter the
FD value stamped on the sensor tag. Default: 0.0
Temperature
Coeff (DTC) One of the values required to characterize the Model 3711 for
the particular sensor it is using. On some sensor tags, this value
is shown as TC. See Section 5.5.1.
Low Density Cal
Value (D1) One of the values required to characterize the Model 3711 for
the particular sensor it is using. See Section 5.5.1.
Low Density Tube
Period (K1) One of the values required to characterize the Model 3711 for
the particular sensor it is using. See Section 5.5.1.
High Density Cal
Value (D2) One of the values required to characterize the Model 3711 for
the particular sensor it is using. See Section 5.5.1.
High Density
Tube Period (K2) One of the values required to characterize the Model 3711 for
the particular sensor it is using. See Section 5.5.1.
