ABSTRACT:
A detector for automatically determining the presence of air in a fluid line comprises a plurality of ON-OFF optical sensors selectively disposed in series along the axis of a portion of an I.V. tube according to their relative light sensitivity and according to their dependence upon direct or refracted light for activation. An alarm condition indicates air-in-line when predetermined individual sensors change their ON or OFF condition in accordance with a microprocessor programmed logic sequence.
