# .BuildSysPro.IBPSA.Fluid.Sensors.EntropyFlowRate

Ideal entropy flow rate sensor

## Information

This model outputs the entropy 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 entropy sout that is used to compute the entropy flow rate Ṡ = ṁ sout is computed using a first order differential equation. See IBPSA.Fluid.Sensors.UsersGuide for an explanation.
