Tests were conducted on a fluidic oscillator for the purpose of determining its potential use as a flowmeter. Water, Bayol 35, and an ethylene glycol-water mixture were used as the test fluids. The effects of setback, aspect ratio, splitter distance, and feedback inlet location on oscillation frequency were investigated. Tests show that the oscillation frequency, when using liquids, is linearly related to volume flow rate. The tests show that the oscillation frequency was insensitive to both density and viscosity in the range investigated.
