摘要
A flow-meter having a sliding lamina interposed between two chambers and movable to vary the flow therethrough in response to deviations in the pressure difference between the chambers to maintain a constant preset pressure difference for accurate measurement of instantaneous flow rates over a wide range. A cam surface relates linear variation in flow rates to non-linear variation in the area of the opening for fluid passage.
