1. A flowmeter for gaseous fluid comprising:
a conduit composed of non-electrically conductive material for passage of an ionized flow of the gaseous fluid therethrough;
an electromagnetic sensor arranged to measure a magnetic field generated about the conduit by the passage of the ionized flow and generate a signal proportional to the magnetic field; and
a de-ionizer for neutralizing the ionized flow downstream from the electromagnetic sensor.
