ABSTRACT:
A method for determining the volume of gas flow in a conduit. Magnetic heads mounted on arms that oscillate in response to pressure changes record magnetic signals on rotating magnetic discs instead of the usual method of recording ink tracks on paper charts. The magnetic signals are then sensed and integrated to volumetric data by means of a computer program. Both ink and magnetic indicia may be made on the same disc if desired.
