Steam Drum Level Transmitter

Somewhere in its programming parameters, one perhaps sets the low value to -350 and the high value to +350. Anything beyond would be an outrage.

Hi

Drum Levels I have had experence with have a constant head which will give a differential pressure to a transmitter in the order of 0 to 49 mBars this is then feed into the DCU as 4 to 20 mAmps. Also the Drum Pressure is measured sent to DCU as 4 to 20 mAmps. The Level and Pressure has "Density Compensation" calculation which give a corrected value at different pressures

Not sure if that is what you are after ???
