Abstract
A device for measuring the mass flow or flow rate of a gas which entrains ions produced by an electrode positioned in the path of the gas flow, this electrode being brought to a certain potential with respect to at least one other electrode also arranged in the flow path.
Claims6
A device for measuring the mass flow or rate flow of a gas, comprising:
- first, second and third electrodes positioned in the path of the gas flow, the first, second and third electrodes being electrically isolated from each other, the second electrode being spaced from the first electrode in the flow direction, the third electrode being spaced from the second electrode in the flow direction;
- a voltage source coupled between the first electrode and the second and third electrodes for producing a corona discharge localized about the first electrode and for creating an electric field such that the ions produced by the first electrode move toward the second electrode, in the direction of the gas flow.
