Endress+Hauser Levelflex FMP53 - The Automatic DC calculation sequence; Manual interface thickness

Levelflex FMP51, FMP52, FMP54 Description of device parameters (operating menu)
Endress+Hauser 135
The "Automatic DC calculation" sequence
If - in the case of interface measurements - the thickness of the upper medium is known at a
certain point of time (e.g. through a manual measurement), the Automatic DC calculation
sequence can be used to calculate the dielectric constant of the upper medium.
Manual interface thickness
Navigation
Setup ® Advanced setup ® Interface ® Autom. DC calc. ® Man. int. thickn.
Meaning
Input of the manually determined interface
thickness UP (i.e. the thickness of the upper
medium).
UP

Input
0 to 200 m (0 to 656 ft)
Factory setting
0 m (0 ft)
Additional information
The measured interface thickness is indicated on the display together with the manual interface
thickness. By comparing these two values the device can automatically adjust the DC value of the
upper medium.
