Figure 4-1. Tank Geometry

The Model 3301 transmitter can be configured for level and volume measurements. The Model 3302 is designed to measure interface level and interface distance as well.

The Rosemount 3300 transmitter can be pre-configured according to the ordering specifications in the Configuration Data Sheet.

The basic transmitter configuration includes setting the tank geometry
