Abstract
A medical infusion testing device has a pair of identical measuring tubes with valves to direct flow to one tube while draining the one tube down to a predetermined level. The level of liquid in the tubes is measured by an optical charge coupled device. A logic device is arranged to measure a spot reading over a small flow or an averaged flow over an entire reading.
