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.

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
3
(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

Features
n Simplified Setup and Calibration—For quick analog
transmitter replacement (4-20mA out only), the
instrument may be configured with default sensor
data, zero Level Offset, differential process SG, and
zero/span procedure only. For full compensation
and diagnostic capabilities, complete sensor data
entry and calibration is recommended.
Using Guided Setup, digital level controller start-up
is straightforward and fast. Level and temperature
alarms, specific gravity tables, calibration trim and
trending are readily configurable. The DLC3010 also
supports re-ranging without a fluid reference.
n Responsive to Small Process Changes—Accurate,
high-gain analog-to-digital conversion enables
measurement of small changes in the process
variable. This allows the DLC3010 to be used in
difficult liquid level, interface, or density
applications. In addition, an adjustable input filter
and output damping help to attenuate
displacer-induced ripple in the output signal due to
liquid turbulence.
n Reduced Temperature Effects—An internal
temperature sensor enables consistent
performance of the digital level controller despite
ambient temperature changes. With a temperature
input signal, either via HART protocol or an RTD
connected to the instrument, the digital level
controller can also automatically compensate for
specific gravity changes due to temperature. A
user-supplied table of up to ten linear segments
may be entered to implement this feature. (A
sample water/steam table is provided in the
DLC3010 instruction manual (D102748X012). The
measured torque tube rate may be manually
pre-compensated for a target process temperature
using the data available in the DLC3010 Device
Description (DD).
n Additional Compensation—The instrument
measurement algorithm corrects for the small
motion of the displacer as buoyancy changes,
allowing it to calculate the true cage or vessel level.
This provides additional accuracy on the shorter
displacers.
n Rugged Construction—Mechanical safeguards
designed into the digital level controller help it to
withstand physical abuse often incurred during
installation or in transport, without compromising
performance. The fully encapsulated printed wiring
boards resist the effects of vibration, temperature,
and corrosive atmospheres. The lever assembly is
pinned at the neutral position when the coupling
access door is open, providing shipping stabilization
for a separate transmitter purchase. Locking set
screws are provided for covers and the access door
handle.
n Easy Maintenance—Field wiring connections are in a
compartment separated from the electronics. This
protects the electronics from any moisture brought
into the housing by the field wiring. This also eases
installation and maintenance. The digital level
controller does not have to be removed to facilitate
troubleshooting or service. Modular construction
(figure 4) allows servicing in the field. However, if it
is necessary to remove the digital level controller for
in-shop maintenance and calibration, field wiring
does not need to be disconnected.
n Alarm Jumper—The DLC3010 digital level controller
includes self-diagnostics that detect an error (e.g.
electronics failure) that would render the process
variable measurement inaccurate. The instrument
can also be configured to indicate a process variable
high or low alarm. When a process variable alarm or
an error is detected the analog output signal is
driven either above or below the normal 4 to 20 mA
range, depending on the user-selectable position of
the alarm jumper. The unit ships from the factory
with the jumper in the high position.

Principle of Operation
The DLC3010 digital level controller is a loop-powered
instrument that measure changes in liquid level, level
of an interface between two liquids, or density of a
liquid. A level, density, or interface level change in the
measured fluid causes a change in the displacer
buoyancy (figure 5). This change is transferred to the
torque tube assembly. As the measured fluid changes,
the torque tube assembly rotates.
The rotary motion of the torque tube is transferred to
the digital level controller lever assembly (figure 5).
The rotary motion moves a magnet attached to the
lever assembly, changing the magnetic field that is
sensed by the Hall-effect sensor. The sensor converts
the magnetic field signal to a varying electronic signal,
which is processed digitally to provide linearity
corrections, sensitivity adjustment, and temperature
compensation.
The signal is interpreted as a buoyancy change by
reference to the stored torque rate, coupling point,
and moment arm data. The buoyancy change in turn is
interpreted as a level, interface, or density change by
reference to stored displacer volume, specific gravity,
and displacer length data. In level or interface modes,
the correction for displacer motion is then added, as
well as user-supplied offset to change the PV reference
from the bottom of the displacer or correct for a
coupling point error.
The resultant primary variable (PV) is then compared
to PV alarm thresholds (if enabled) and used to set
status bits and/or trigger the analog alarm current. If
the alarm is not triggered, the PV is used to generate
4-20 mA analog and 0-100% range digital signals by
reference to the stored upper and lower range values.
The resultant analog command is limited at the
saturation values to allow discrimination between
saturated and alarm signals.

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.

Installation
A 249 sensor may be shipped with the DLC3010 digital
level controller installed or they may be shipped
separately.
When shipping a skid mounted system, where the
displacer cannot be restrained, it is recommended that
the transmitter be uncoupled and the lever assembly
locked to prevent damage. The transmitter must be
re-coupled at commissioning, and a zero-trim will be
required.
Dimensions for the DLC3010 and 249 sensor product
construction are shown in figure 9 and tables 6 and 7.
Dimensions of other combinations are available upon
request.
