A method of reducing fluid flow measurement artifacts associated with polarographic oxygen sensors is described which consists of mounting a miniature polarographic electrode on the end of a vibrating piezoelectric bender element. The electrode sensing area is vibrated at a high speed which causes a reduction in measurement error due to flow eddies in solution as well as greatly increasing the electrode sensitivity.
