Method and apparatus for measuring minute gas flows and/or accumulations wherein a gas flow is bubbled through a defined path in separated form and a sensor is used to detect and count each bubble. The bubble count signal can be used to calculate gas accumulation, or to calculate gas flow rate if made during a defined time period, or to meter the flow of the gas to a point of utilization.
