1.Functions

Buoyancy displacement measurement: Work with 249 displacer sensor. The buoyancy change of the displacer is converted into torque tube rotation, then calculated to get liquid level, liquid-liquid interface or liquid density value. www.plcva.com
HART communication & analog output: Output 4–20mA analog signal superimposed with HART digital protocol, transmit measurement value to PLC/DCS.
Local operation interface: LCD display plus 4 push buttons, support on-site configuration, calibration, trend recording and alarm setting without handheld communicator.
Dynamic temperature compensation: Built-in temperature sensor automatically compensates density variation caused by medium temperature change to maintain measuring accuracy.
NE107 compliant device diagnostics: Monitor internal circuit and sensor health; generate alarm for abnormal conditions, support predictive maintenance. www.plcva.com
SIL2 capable version (DLC3100 SIS optional): Suitable for safety instrumented systems; multiple explosion-proof certifications (Ex ia / Ex d), IP65 enclosure.
Modular mechanical structure: Compatible with original Fisher 249 displacer assembly and partial third-party displacer units, easy retrofit replacing old DLC3010.
Loop-powered design, no separate AC power supply required.

This digital displacer level controller is used for heavy-duty liquid level / interface measurement in process industries. www.plcva.com

Industries: Oil & gas, petrochemical, chemical refining, power, offshore platform.
Typical measuring media: Oil-water interface, high-temperature / high-pressure liquid, viscous fluid.
Typical scenarios: Separator tank, reactor vessel, condensate drum, storage tank, phase separation tank.
Core purpose: Precisely measure liquid level or oil-water interface, feed back signal to process control system for continuous level regulation and high/low level safety interlock.
Working advantage: Stable performance under high pressure, high temperature, viscous or dirty medium where radar or guided wave level instruments are not applicable.
