The Rosemount 3308 transmitter can be configured for level, volume,
interface level, and interface distance measurements.
The Rosemount 3308 transmitter can be pre-configured according to the
ordering specifications in the Configuration Data Sheet.
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.
