Abstract
Apparatus for measuring the mass flow of a fluid comprises a first ionizing electrode which, in use, is located in the path of fluid flow and, when energized, ionizes said fluid. A second substantially cylindrical, hollow collector electrode extends around said first electrode so that, in use, the ions produced by the first electrode migrate to the second electrode. The second electrode includes a plurality of conductive rings which are spaced apart in the direction of fluid flow and insulating material is interposed between adjacent rings, but is arranged so as not to be exposed to the ions migrating to the rings in use. Means is responsive to the amount of ion migration to the various conductive rings for measuring the displacement of the ions by the fluid flowing past the electrodes, the displacement being dependent upon the mass flow of the fluid.
