Rosemount 3301 GWR Level + Interface

Rosemount1 configuration

Configure Your Rosemount 3301 Guided Wave Radar Level + Interface Transmitter

Guided wave radar level + interface transmitter, sister product to the 3300. Same probe-based GWR principle with dual measurement: liquid-air interface (level) AND liquid-liquid interface (e.g., oil-water separator). Reports both as separate 4-20 mA outputs or HART variables.

3301 Guided Wave Radar Level + Interface

Variant of the 3300 GWR specifically tuned for level AND interface measurement on two-phase liquids (oil/water interfaces, settling tanks, separator vessels). Same probe and electronics platform as the 3300; interface-detection firmware identifies both the upper-product level AND the lower-fluid interface in one signal. Reports both as separate 4-20 mA outputs or HART variables. Best in applications where you previously needed two separate level transmitters (or a displacer + a level transmitter).
