Tank type and tank bottom type
The Rosemount 5400 Series transmitter is optimized according to the Tank Type and Tank
Bottom Type configuration by automatically setting some parameters to predefined default
values.
Select Tank Bottom Type Flat Inclined if the bottom inclination is between 10 and 30 degrees. If
the inclination is less than 10 degrees, but there are disturbing objects on the tank floor (like
heating coils) within the radar beam, this selection should also be used. If the inclination is
greater than 30 degrees, use the Cone Tank Bottom Type.
