  • Boiler Drum Level Transmitter Calibration - Technical Note

    With the drum level transmitter properly calibrated, the midpoint of the actual readout range, typically –15 to 15 in., is zero, or mid-scale. This generally corresponds to the desired setpoint for the drum level controller. However, in some applications the setpoint may be less than zero and depends on your experience with a particular boiler.Learn More
