ABSTRACT OF DISCLOSURE A flowmeter capable of accurately measuring and trans- mitting extremely low flow rates, the meter including a ver- tically-positioned flow tube having a ferromagnetic ball therein which is subjected to the force of gravity as well as to the drag force imposed by the flow of fluid to be metered. Asso- ciated with the flow tube is a position sensor typically constituted by a light source projecting a beam across the translucent tube that is intercepted by a photosensor yielding a control signal when the beam is obscured by the ball. The ball is also subjected to a magnetic force produced by an electromagnet energized by a current controller governed by the control signal, which force seeks to displace the ball away from the light beam. Thus the ball acts as a force summing junction and is caused to assume a position depending on the vector resultant of the co-acting drag, gravitational and magnetic forces. The time average current generated by the controller is a function of the flow rate and is indi- cated to afford a flow rate reading. -1-
