3.15.4 Measurement setup for interface measurement

The master-slave combination is suitable for interface measurement. Requirements for a
functioning measurement are:
• Tanks with variable level
• Media with constant density
• Interface always between the measuring points
• Total level always above the upper measuring point
The mounting distance h of the two sensors should be at least 10%, preferably 20%, of the final
value of the sensor measuring range. A greater distance increases the accuracy of the interface
measurement. The interface measurement is possible in open as well as in closed tanks.
