FISHER DLC3010 Series digital level controllers are used with level sensors to measure liquid level

product description

DLC3010 Digital Level Controllers
DLC3010 digital level controllers (figure 1‐1) are used with level sensors to measure liquid level, the level of interface between two liquids, or liquid specific gravity (density). Changes in level or specific gravity exert a buoyant force on a displacer, which rotates the torque tube shaft. This rotary motion is applied to the digital level controller, transformed to an electrical signal and digitized. The digital signal is compensated and processed per user configuration requirements, and converted back to a 4‐20 mA analog electrical signal. The resulting current output signal is sent to an indicating or final control element.


DLC3010 digital level controllers are communicating, microprocessor‐based level, interface, or density sensing instruments. In addition to the normal function of providing a 4‐20 milliampere current signal, DLC3010 digital level controllers, using the HART communications protocol, give easy access to information critical to process operation. You can gain information from the process, the instrument, or the sensor using a Field Communicator with device descriptions (DDs) compatible with DLC3010 digital level controllers. The Field Communicator may be connected at the digital level controller or at a field junction box.

Using the Field Communicator, you can perform several operations with the DLC3010 digital level controller. You can interrogate, configure, calibrate, or test the digital level controller. Using the HART protocol, information from the field can be integrated into control systems or be received on a single loop basis.

DLC3010 digital level controllers are designed to directly replace standard pneumatic and electro‐pneumatic level transmitters. DLC3010 digital level controllers mount on a wide variety of caged and cageless 249 level sensors. They mount on other manufacturers' displacer type level sensors through the use of mounting adaptors.

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.
