Abstract: The scientific community has known about Fluidic Oscillation as a measurement technology for many years. Recent advances in this technology now make this a highly robust, cost-effective solution to metering needs. This paper will discuss the advances and benefits. Based on Bernoullis Theory - A slow moving high pressure gas becomes fast moving low pressure gas at the nozzle exit forming a jet of gas. The jet, once formed can be controlled by the Coanda effect using an obstacle in the flow that is designed to optimize the performance of the meter. Controlling the jet path enables formation of feedback nodes of pressure on either side of the jet. This provides a predictable oscillation of the jet.
