Abstract
Mass flow measuring apparatus includes an ionizing electrode and an ion collecting electrode located downstream from the ionizing electrode. The ions are allowed to migrate at the same speed with the mass fluid flow and are 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.
