Abstract: A fluid flow sensor uses pairs of acoustic transducers to generate quasi-helical acoustic beams reflected multiple times from an inside surface of a pipe. The transducers are arranged so that each two pairs generate counter-rotating beams. When fluid flowing in the pipe has both a rotary and an axial flow component the rotary component adds to the apparent flow rate measured in one rotational direction and subtracts from that measured in the other. Hence, a combination of transit time measurements along the two paths can be used to cancel out the effects of the rotary flow component and yield a measure of the rate of flow along the pipe axis. In some cases multiple probes are used to increase the amount of flowing fluid that is sampled.

Abstract: A wide range continuous diluter for diluting gases that contain small particles to allow subsequent measurement of the diluted gases with an instrument is provided. A dilution gas inlet receives a dilution gas, and a sample gas inlet receives a sample gas. A flow meter measures the sample gas flow rate. A mixer receives and mixes the dilution gas and the sample gas at a dilution ratio. An instrument flow outlet provides a well-defined flow into the instrument from the mixture flow.
