4.7 Interface measurement
The master/slave combination is suitable for interface measurement
Requirements for a functioning measurement are:
•
Vessel with changing level
•
Products with steady density
•
Interface always between the measurement points
•
Total level always above the upper measurement point
The mounting distance h of the two sensors should be at least 10 %,
better 20 %, of the final value of the sensor measuring range. A bigger
distance increases the accuracy of the interface measurement.
