ABSTRACT:
An ion collecting electrode is located downstream of ionizing means, the ions migrating at the same speed as the mass flow and being collected by the collecting electrode. The transit time of the ions over the distance between a predetermined point of the path of fluid and the collecting electrode is measured. A grounded shielding electrode protects the ion collecting electrode from being attacked by the electro-magnetic wave inevitably generated by the ionizing means upon operation of the same.
