Fieldbus digital level controller

Provides easy access to information that enables accurate control with less downtime

Emerson Process Management's Fisher® FIELDVUE™ DLC3020f fieldbus digital level controller provides new levels of performance and information access to help users improve operations.

In addition to displacement sensor technology for measuring liquid level or the level of interface between two liquids, the DLC3020f uses the digital FOUNDATION fieldbus communication protocol to deliver diagnostics, alerts, and other information that helps users improve performance, while avoiding unexpected downtime. Digital communication also makes it easy to configure, calibrate, and test the DLC3020f using Emerson's AMS Suite software or 475 Field Communicator, and to integrate the instrument with new or existing control systems.

Guided setup and calibration leads the user through the instrument setup, process fluid selection, and calibration in an easy-to-use format. The capability to easily select and define process fluids allows on-the-fly fluid changes for batch or continuous applications without calibration, saving time and recalibration costs.

The instrument stores up to 30 logs including calibration, instrument setup, and process fluid data, that can be saved for future reference or re-use. Advanced electronics provide increased performance and reliability, and process fluid temperature can be used when needed for density compensation to maintain process-variable accuracy.

The DLC3020f is designed to directly replace pneumatic, analogue, or HART® transmitters/controllers. To provide additional flexibility, it can be mounted on a wide variety of Fisher 249 cageless and caged level sensors, as well as on other displacer type level sensors through the use of mounting adaptors
