CONFIGURATION
PARAMETERS
The Rosemount 3301 transmitter can be configured for level and volume
measurements. The Rosemount 3302 is designed to measure interface level
and interface distance as well.
The 3300 transmitter can be pre-configured according to the ordering
specifications in the Configuration Data Sheet.
Basic Configuration The basic transmitter configuration includes setting the tank geometry
parameters. For interface measurements the dielectric constant of the top
liquid must also be given. For some applications with heavy vapor, the vapor
dielectric must be given as well.
