ABSTRACT:
An ionization flow meter which can determine with high accuracy the flow of a gas expressed as a gas velocity, volume flow, or mass flow and substantially independently of pressure, temperature and, as the case may be, moisture content. By applying the theory of corona discharges, data relating to the flow-determining factors such as ion mobility and gas density can be derived from the known measured voltage and current values using electronic means. For example, the slope S of the I-V characteristic curve can be determined from the measured values of voltage V and current I.
