DLC3010 Digital Level Controller

Table 1‐1. DLC3010 Digital Level Controller Specifications (continued)
Minimum Differential Specific Gravity (continued)
See 249 sensor specifications for standard displacer
volumes and standard wall torque tubes. Standard
volume for 249C and 249CP sensors is
∼
980 cm
3
(60
in
3
), most others have standard volume of
∼
1640 cm
3
(100 in
3
).
Operating at 5% proportional band will degrade
accuracy by a factor of 20. Using a thin wall torque
tube, or doubling the displacer volume will each
roughly double the effective proportional band.
When proportional band of the system drops below
50%, changing displacer or torque tube should be
considered if high accuracy is a requirement.
Mounting Positions
Digital level controllers can be mounted right‐ or
left‐of‐displacer, as shown in figure 2‐5.
Instrument orientation is normally with the coupling
access door at the bottom, to provide proper
drainage of lever chamber and terminal
compartment, and to limit gravitational effect on the
lever assembly. If alternate drainage is provided by
user, and a small performance loss is acceptable, the
instrument could be mounted in 90 degree rotational
increments around the pilot shaft axis. The LCD meter
may be rotated in 90 degree increments to
accommodate this.

1. A = No degradation during testing. B = Temporary degradation during testing, but is self‐recovering. Specification limit = +/- 1% of span.
2. HART communication was considered as “not relevant to the process” and is used primarily for configuration, calibration, and diagnostic purposes.
