FIELDVUE ® DLC3000 Series Digital Level Controllers

DLC3000 Digital Level Controllers Description FIELDVUE® DLC3000 Series digital level controllers (figure 1) are 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.
DLC3000 Series digital level controllers are communicating, microprocessor-based instruments 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, DLC3000 Series digital level controllers, using the HART® communications protocol, give easy access to information critical to process operation. You can obtain information about the process, instrument, or sensor using the Model 375 Field Communicator. Advanced user-interface capabilities are enabled by AMSTM Suite: Intelligent Device Manager. The DLC3000 Series can be used in analog or HART digital signaling mode with the Emerson Process Management DeltaVTM 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 through the HART protocol. Information from the field can be integrated into control systems or be received on a single loop basis.
DLC3000 Series digital level controllers are designed to directly replace standard pneumatic and electronic level transmitters. Type DLC3010 digital level controllers mount on a wide variety of Fisher® 249 Series cageless and caged level sensors.

Operating Influences

Power Supply Effect: Output changes <±0.2% of full scale when supply varies between min. and max voltage specifications.
Transient Voltage Protection: The loop terminals are protected by a transient voltage suppressor. The specifications are as follows:


Pulse Waveform
 Max VCL
(Clamping
Voltage) (V)		 Max IPP
(Pulse Peak
@ Current) (A)
Rise Time (μs) Decay to 50% (μs)
10 1000 93.6 16
8 20 121 83
Note: μs = microsecond
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 3). 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.
Electromagnetic Interference (EMI): Tested per IEC 61326-1 (Edition 1.1). Complies with European EMC Directive. Meets emission limits for class A equipment (industrial locations) and class B equipment (domestic locations). Meets immunity requirements for industrial locations (Table A.1 in the IEC specification document). Immunity performance is shown in table 1.

Supply Requirements (See figure 5)

12 to 30 volts dc; instrument has reverse polarity protection.
A minimum compliance voltage of 17.75 is required to guarantee HART communication.

Compensation

Transducer compensation: for ambient temperature.
Density parameter compensation: for process temperature (requires user-supplied tables).

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 Series sensor specifications for standard displacer volumes and standard wall torque tubes. Standard volume for 249C and 249CP series is ~980 cm3 (60 in3), most others have standard volume of ~1640 cm3 (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 controllers can be mounted right- or left-of-displacer, as shown in figure 9.
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.

Features

  • 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.

Through the use of an electronic Setup Wizard, digital level controller start-up is straightforward and fast. Level and temperature alarms, specific gravity tables, calibration trim and trending are readily configurable. DLC3000 Series digital level controllers also support re-ranging without a fluid reference.

  • Responsive to Small Process Changes—Accurate, high-gain analog-to-digital conversion enables measurement of small changes in the process variable. This allows DLC3000 Series digital level controllers 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.
  • 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. (An sample water/steam table is provided in the FIELDVUE DLC3000 Series Digital Level Controls instruction manual, Form 5631). The measured torque tube rate may be manually pre-compensated for a target process temperature using the data available in the DLC3000 Device Description (DD).
  • 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.
  • 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.
  • 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 2) 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.
  • Alarm Jumper—DLC3000 Series digital level controllers include 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.

       Close Section Above

Principle of Operation The DLC3000 Series digital level controllers are loop-powered instruments 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 4). 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. 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 Series Level Sensors 249 Series level sensors used with Type DLC3010 digital level controllers are available in both caged and cageless configurations. Figure 7 shows a Type DLC3010 digital level controller 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.
