Steam Drum Level Calibration Range

[Linus Jr]

we have a 1151rosemount transmitter with impulse tubbing and condensate pot and we are replacing the old 1151 transmitter with a new 3051CD model with the same impulse tubbing setup, so how can I calculate the calibration range of the drum with the drum dimensions. ( the high-pressure side nozzle is 5inch elevated from the base of the drum.
