D Distance from liquid surface to lower edge of the flange
Delta Measuring error
If there are fast changes in pressure, there may be an additional error, since the mesured reference distance is
filtered with the time constant of the level measurement. In addition, conditions of imbalance - for example
due to heating - may cause density gradients within the medium and condensation of steam at the probe. As
a result, the level readings at different locations inside the tank may vary slightly. Caused by this application
influences the measuring error may be increased by a factor up to 2 to 3.
