Abstract

1512235 Measuring gas flow-rate J ZIZINE 13 May 1975 20176/75 Heading G1N A gas flowmeter includes at least three conductive electrodes 1, 2, 3 in the form of metal gratings arranged perpendicularly to, and spaced apart of, the direction of gas flow 8 and di-electrically insulated one from the other. Electrode 1 has a radio-active coating (not shown) so as to provide a source of ions and a voltage source 12 provides an electric field between the electrodes 1, 2, such that ions produced by the first electrode move towards the second electrode and ions traversing the second electrode are collected on the third. The current I 3 from the collector electrode 3 is a function of gas flow speed and in order to obtain a direct measurement thereof the source 12 is regulated so that its output voltage bears a constant ratio to the current I 2 collected on the second electrode, using the resistors 11, 13, 14 and differential amplifier 15. Fig. 4 (not shown), illustrates an embodiment for bi-directional sensing by addition of a pair of electrodes (19, 20) symmetrical with the second and third electrodes relative to the first electrode. A microammeter (9) indicates the difference between currents collected at the third and fifth electrodes and which represents gas flowrate. In this embodiment as in that of Fig. 2 (not shown), the source of ions is a corona discharge around electrode 1 produced by a high voltage source (5).
