.Annex60.Fluid.Sensors.VolumeFlowRate

Information

This model outputs the volume flow rate flowing from port_a to port_b. The sensor is ideal, i.e., it does not influence the fluid. If the parameter tau is non-zero, then the measured density that is used to convert the mass flow rate into volumetric flow rate is computed using a first order differential equation. Setting tau=0 is not recommend. See Annex60.Fluid.Sensors.UsersGuide for an explanation.

Revisions

• January 18, 2016 by Filip Jorissen:
  Using parameter tauInv since this now exists in Annex60.Fluid.Sensors.BaseClasses.PartialDynamicFlowSensor. This is for #372.
• August 31, 2013, by Michael Wetter:
  Removed default value tau=0 as the base class already sets tau=1. This change was made so that all sensors use the same default value.
• 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. Implementation is based on Modelica.Fluid.
