Fisher™ FIELDVUE™ DLC30100 Digital LevelController

The FIELDVUE DLC3010 digital level controller is used
with level sensors to measure liquid level, the level of
the interface between two liquids, or liquid specific
gravity (density). Changes in level or specific gravity
exert a buoyant force on a displacer, which rotates a
torque tube shaft. The digital level controller converts
this rotational motion to an electronic signal

The DLC3010 is a communicating,
microprocessor-based instrument that can be
configured to sense the level, interface level, or
density of liquids.
The DLC3010, using HART® communications protocol,
gives easy access to information critical to process
operation. You can obtain information about the
process, instrument, or sensor using an Emerson Field
Communicator. The DLC3010 can be used in analog or
HART digital signaling mode with the Emerson
Automation Solutions DeltaV™ system.

The DLC3010 digital level controller is designed to directly replace standard pneumatic and electronic level transmitters. It mounts on a wide variety of Fisher249 caged and cageless level sensors.

249 Level Sensors

 

249 level sensors used with the DLC3010 digital level
controller are available in both caged and cageless
configurations. Figure 6 shows a DLC3010 mounted on
a caged 249 sensor. Caged sensors provide more
stable operation than do cageless sensors for vessels
with internal obstructions or considerable internal
turbulence. Cageless sensors are generally used on
specific gravity and interface control applications
requiring large displacers that are more easily
accommodated by flange connections up to 8 inches.
The availability of many different displacer stem
lengths permits lowering the displacer down to the
most advantageous depth in the vessel.
