.BuildSysPro.IBPSA.Fluid.Sensors.SpecificEntropyTwoPort

Information

This model outputs the specific entropy of the 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.

Revisions

• February 25, 2020, by Michael Wetter:
  Changed icon to display its operating state.
  This is for #1294.
• January 18, 2016 by Filip Jorissen:
  Using parameter tauInv since this now exists in IBPSA.Fluid.Sensors.BaseClasses.PartialDynamicFlowSensor. This is for #372.
• August 31, 2013, by Michael Wetter:
  Corrected wrong computation of s and sMed.
• June 3, 2011 by Michael Wetter:
  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.
• September 29, 2009, by Michael Wetter:
  First implementation.
