modelHeatMeter
Measures thermal energy provided between supply and return pipes
Extends from BaseClasses.PartialDynamicFlowSensor, Modelica.Icons.RoundSensor.
Information
This model measures thermal energy provided between a supply and return pipe.
It measures the capacity flow rate of the heat transfer fluid and the change in its
temperature compared to an external temperature measurement that is input into the port
TExt. The sensor does not influence the fluid.
The rate of heat flow is calculated as Q̇ = ṁ cp (T - TExt).
