An apparatus and method for use in determining one or more fluid flow properties of a fluid in a conduit is disclosed. The apparatus includes a substrate including a barrier, a first flow sensor coupled to the substrate and a second flow sensor coupled to the substrate. The first flow sensor is located at a first sensor distance from a first barrier surface, and the second flow sensor is located a second sensor distance from the second barrier surface. The first sensor distance is substantially equal to the second sensor distance. In operation, the first flow sensor produces a first sensor signal, and the second flow sensor produces a second sensor signal. The direction of flow for the fluid is determined by comparing the first sensor signal to the second sensor signal.

A system for measuring size segregated mass concentration of an aerosol. The system includes an electromagnetic radiation source with beam-shaping optics for generation of a beam of electromagnetic radiation, an inlet sample conditioner with adjustable cut-size that selects particles of a specific size range, and an inlet nozzle for passage of an aerosol flow stream. The aerosol flow stream contains particles intersecting the beam of electromagnetic radiation to define an interrogation volume, and scatters the electromagnetic radiation from the interrogation volume. The system also includes a detector for detection of the scattered electromagnetic radiation an integrated signal conditioner coupled to the detector and generating a photometric output, and a processor coupled with the conditioner for conversion of the photometric output and cut-size to a size segregated mass distribution.
