In addition to displacement sensor technology for measuring liquid level or the level of interface between two liquids, the Fieldvue DLC3020f (photo) uses the digital Foundation Fieldbus communication protocol to deliver diagnostics, alerts, and other information. The capability to select and define process fluids allows on-the-fly fluid changes for batch or continuous applications without calibration. The DLC3020f is designed to directly replace pneumatic, analog or HART transmitters and controllers. — Emerson Process Management, St. Louis, Mo.
