# .AixLib.Fluid.Sensors.EnthalpyFlowRate

Ideal enthalphy flow rate sensor

## Information

This model outputs the enthalphy flow rate of the medium in the flow between fluid ports. The sensor is ideal, i.e., it does not influence the fluid.

If the parameter `tau` is non-zero, then the measured specific enthalpy hout that is used to compute the enthalpy flow rate Ḣ = ṁ hout is computed using a first order differential equation. See AixLib.Fluid.Sensors.UsersGuide for an explanation.

For a sensor that measures the latent enthalpy flow rate, use AixLib.Fluid.Sensors.LatentEnthalpyFlowRate.

## Revisions

- October 19, 2020, by Antoine Gautier:
  Changed default value for `tau` from `1` to `0`.
  This is for #1406.
- February 25, 2020, by Michael Wetter:
  Changed icon to display its operating state.
  This is for #1294.
- January 26, 2016, by Michael Wetter:
  Made unit assignment of output signal final.
- January 18, 2016 by Filip Jorissen:
  Using parameter `tauInv` since this now exists in AixLib.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 can improve the numerics.
- April 9, 2008 by Michael Wetter:
  First implementation. Implementation is based on enthalpy sensor of `Modelica.Fluid`.
