Instrument Description
The FIELDVUE DLC3020f digital level controller (figure 27) is a fieldbus communicating instrument used to measure
liquid level or the level of interface between two liquids using displacement sensor technology.

In addition to the normal function of reporting process level PV, the DLC3020f, using FOUNDATION fieldbus protocol,
gives easy access to information critical to process operation and will readily integrate into a new or existing control
system. AMS Device Manager or the 475 Field Communicator can be used to configure, calibrate, or test the digital
level controller.
The DLC3020f is also designed to directly replace pneumatic, analog, or HARTr transmitters/ controllers. It can be
mounted on a wide variety of 249 cageless and caged level sensors as well as on other displacer type level sensors
through the use of mounting adaptors.
249 Caged Sensors (see table 11)
D 249, 249B, 249BF, 249C, 249K, and 249L sensors side‐mount on the vessel with the displacer mounted inside a cage
outside the vessel.
249 Cageless Sensors (see table 12)
D 249BP, 249CP, and 249P sensors top‐mount on the vessel with the displacer hanging down into the vessel.
D 249VS sensor side‐mounts on the vessel with the displacer hanging out into the vessel.
D 249W wafer‐style sensor mounts on top of a vessel or on a customer‐supplied cage.
Specifications
Specifications for DLC3020f are shown in table 6. Specifications for 249 sensors are shown in table 8.
