modelSpecificEnthalpyTwoPort
Ideal two port sensor for the specific enthalpy
Extends from IBPSA.Fluid.Sensors.BaseClasses.PartialDynamicFlowSensor, Modelica.Icons.RotationalSensor.
Information
This model outputs the specific enthalpy of a passing fluid.
The sensor is ideal, i.e. it does not influence the fluid.
If the parameter tau is non-zero, then its output
is computed using a first order differential equation.
Setting tau=0 is not recommend. See
IBPSA.Fluid.Sensors.UsersGuide for an explanation.

Using parametertauInvsince this now exists in IBPSA.Fluid.Sensors.BaseClasses.PartialDynamicFlowSensor. This is for #372. -

Revised implementation to add dynamics in such a way that the time constant increases as the mass flow rate tends to zero. This significantly improves the numerics. -
