Level measurement (ToF Tool) Cerabar S/Deltabar S
76 Endress+Hauser
8.2 "Linear" level type
8.2.1 Calibration with reference pressure – wet calibration
Example:
In this example, the level in a tank should be measured in m
3
. The maximum level is 3 m. The
pressure range is set to 0 to 300 mbar.
Prerequisite:
• The measured variable is in direct proportion to the pressure.
• The tank can be filled or emptied.
