.Buildings.Fluid.Sensors.PPM

Information

This model outputs the trace substance concentration in ppm contained in the fluid connected to its port. The sensor is ideal, i.e., it does not influence the fluid.

The parameter MM is the molar mass of the trace substance. For a list of molar masses, see Modelica.Media.IdealGases.Common.SingleGasesData and Modelica.Media.IdealGases.Common.FluidData.

To measure PPM in a duct or pipe, use Buildings.Fluid.Sensors.PPMTwoPort rather than this sensor. Read the Buildings.Fluid.Sensors.UsersGuide prior to using this model to see about potential numerical problems if this sensor is used incorrectly in a system model.

Assumptions

This sensor assumes that the concentration C of the medium is in mass fraction. Otherwise, the conversion to ppm will be wrong.
