modelDifferenceTwoPhaseSensorSensorSelect
Sensor for selectable quantatiy difference of two phase media
Extends from ThermofluidStream.Utilities.DropOfCommonsPlus (Extend this to use 'dropOfCommons', 'instanceName', 'displayInstanceName' and 'displayParameters').
Information
Sensor for measuring the difference of the vapor quality between two fluid streams.
This sensor can be connected totwo fluid streams without a junction.
