8.9.2 "In pressure" level selection
Calibration with reference pressure (wet calibration)
Example:
In this example, the level in a tank should be measured in "m". The maximum level is 3 m (9.8
ft). The pressure range is due to the filling height and the density.
Prerequisite:
• The measured variable is in direct proportion to the pressure.
• The tank can be filled and emptied.
The values entered for "Empty calib. (028)/Full calib. (031)" and the pressures present at the
device must be at least 1% apart. The value will be rejected, and a warning message
displayed, 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.
