Level measurement (via local operation and FieldCare) Cerabar S/Deltabar S/Deltapilot S FOUNDATION Fieldbus
110 Endress+Hauser
9.3 "Level easy height" level selection
9.3.1 Calibration with reference pressure – wet calibration
Example:
In this example, the volume in a tank should be measured in liters. The maximum volume of
1000 liters (264 US gal) corresponds to a level of 4.5 m (15 ft). The minimum volume of 0 liters
corresponds to a level of 0.5 m (1.6 ft) since the device is mounted below the level lower-range
value. The density of the fluid is 1 kg/dm
3
.
Prerequisite:
• The measured variable is in direct proportion to the pressure.
• The tank can be filled and emptied.
!
Note!
• See also Operating Instructions for Deltabar S (BA00301P) or Cerabar S (BA00302P), "Level
measurement" section or Deltapilot S (BA00372P), "Level measurement" section.
• The values entered for EMPTY CALIB./FULL CALIB., EMPTY PRESSURE/FULL PRESSURE and
EMPTY HEIGHT/FULL HEIGHT must be at least 1% apart for the "Level easy height" level mode.
The value will be rejected with a message if the values are too close together. Further limit values
are not checked; i.e. the values entered must be appropriate for the sensor and the measuring task
so that the measuring device can measure correctly.
