modelPPM
Test model for the extra property sensor outputting PPM
Extends from Modelica.Icons.Example (Icon for runnable examples).
Information
This example tests the sensors that measure trace substances using an output in parts per million. Various configurations with and without flow reversal and with or without dynamics are tested.
