3.15.3 Measurement setup for density measurement

The master-slave combination is suitable for density measurement. Requirements for a
functioning measurement are:
• Tanks with variable level
• Distance between the measurement points as large as possible
• 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 density
measurement. Slight density changes cause only slight changes of the measured differential
pressure. The measuring range must hence be selected accordingly. The density measurement
is possible in open as well as in closed tanks.
