Fisherr FIELDVUEt DLC3010 Digital Level
Controller

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. In addition to the normal function of
providing a 4 to 20 milliampere current signal, the
DLC3010, using HART
gives easy access to information critical to process
operation. You can obtain information about the
process, instrument, or sensor using the 475 or 375
Field Communicator. The DLC3010 can be used in
analog or HART digital signaling mode with the
Emerson Process Management DeltaVt system.

The connection for HART communication may be
made at any point in the field wiring that meets the
HART impedance requirements. Configuration,
calibration, diagnostics, parameter review, signal
monitoring and alert monitoring are all available

R

communications protocol,

W7977-1

through the HART protocol. Information from the field
can be integrated into control systems or be received
on a single loop basis.

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

Available Configurations

DLC3010 Digital Level Controller:

Mounts on caged and cageless 249 sensors. See
tables 4 and 5 and sensor description.

Function: Transmitter

Communications Protocol: HART

Input Signal

Level, Interface, or Density: Rotary motion of torque
tube shaft proportional to changes in liquid level,
interface level, or density that change the buoyancy
of a displacer.

Process Temperature: Interface for 2- or 3-wire
100 ohm platinum RTD for sensing process
temperature, or optional user-entered target
temperature to permit compensating for changes in
specific gravity

Output Signal

Analog: 4 to 20 milliamperes DC (

J direct

action—increasing level, interface, or density
increases output; or

J reverse action—increasing

level, interface, or density decreases output)

High saturation: 20.5 mA
Low saturation: 3.8 mA
High alarm: 22.5 mA
Low Alarm: 3.7 mA

Only one of the above high/low alarm definitions is
available in a given configuration. NAMUR NE 43
compliant when high alarm level is selected.

Digital: HART 1200 Baud FSK (frequency shift keyed)

HART impedance requirements must be met to
enable communication. Total shunt impedance
across the master device connections (excluding the
master and transmitter impedance) must be between

230 and 1100 ohms. The transmitter HART receive
impedance is defined as:

Rx: 42K ohms and
Cx: 14 nF

In point-to-point configuration, analog and digital
signalling are available. The instrument may be
queried digitally for information, or placed in Burst
mode to regularly transmit unsolicited process
information digitally. In multi-drop mode, the output
current is fixed at 4 mA, and only digital
communication is available.

Ambient Temperature: The combined temperature
effect on zero and span without the 249 sensor is less
than 0.03% of full scale per degree Kelvin over the
operating range -40 to 80_C (-40 to 176_F)

Process Temperature: The torque rate is affected by
the process temperature (see figure 1). The process
density may also be affected by the process
temperature.

Process Density: The sensitivity to error in knowledge
of process density is proportional to the differential
density of the calibration. If the differential specific
gravity is 0.2, an error of 0.02 specific gravity units in
knowledge of a process fluid density represents 10%
of span.

Minimum Differential Specific Gravity

With a nominal 4.4 degrees torque tube shaft
rotation for a 0 to 100 percent change in liquid level
(specific gravity=1), the digital level controller can be
adjusted to provide full output for an input range of
5% of nominal input span. This equates to a minimum
differential specific gravity of 0.05 with standard
volume displacers.

See 249 sensor specifications for standard displacer
volumes and standard wall torque tubes. Standard
volume for 249C and 249CP is ∼980 cm
most others have standard volume of ∼1640 cm

(60 in3),

3

(100 in3).

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 controller can be mounted right- or
left-of-displacer, as shown in figure 8.

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.
