Claim 0:
1. A housing assembly configured for a fluid sensor assembly, comprising:
a housing having a first sensing volume and a second sensing volume;
a fluid port attached to the housing and having at least a first fluid aperture and a second fluid aperture;
at least one porous membrane assembled between the fluid port and the housing, the at least one porous membrane covering the first and second fluid apertures;
the first sensing volume comprising a vertically-oriented waveguide, the first sensor volume being fluidly coupled to an exterior of the housing through the first fluid aperture, the first aperture port having an area smaller than an area of a cross-section of the waveguide; and
the second sensing volume being coupled to the exterior of the housing through the second fluid aperture, the second fluid aperture having an area larger than an area of a cross-section of the second sensing volume;
wherein the fluid port and the at least one porous membrane internally isolate the first sensing volume from the second sensing volume.
