Calibration of a leveltrol for an interface level measurement


#1

Fill the leveltrol chamber 100% with the lower density liquid and adjust its zero for 4.00mA output.
Drain the liquid and fill the leveltrol chamber 100% with the higher density liquid and adjust its span for 20.00 mA output.

The transmitter on line measures the percentage of higher density liquid in the lower density liquid at a known height.
