This paper suggests a method for measuring current velocity of gases on new principle which uses ion. First of all, the current of fluid under test is ionized by corona discharge made by a transformer, then it is led into two absorbers, which are put keeping some distance each other, but have some pulsating electric field. Passing through their two absorbers, the fluid arrives at an ion receiver, which catches ions escaped from them. If we change the distance between their absorbers, the quantity of ion catched by the receiver changes periodically. Measuring the change of the distance between their two absorbers for one period, we can know the fluid velocity by the following relation. w=λf where w : current velocity of gases λ : the change of the distance between their two absorbers in one period f : frequency of the pulsating electric field
