Abstract

Embodiments disclosed herein provide apparatuses and methods for verifying dispense of a fluid from a dispense nozzle. According to one method, a path of electromagnetic radiation from a source to a receiver is obstructed with the fluid dispensed from the dispense nozzle. The intensity of the electromagnetic radiation received by the receiver is measured. The measured intensity is compared with a predetermined intensity to verify the dispense of fluid from the dispense nozzle. One apparatus for verifying dispense of a fluid comprises a source of electromagnetic radiation, and a receiver of the electromagnetic radiation from the source of the electromagnetic radiation operatively associated with the source of the electromagnetic radiation such that the electromagnetic radiation from the source is received by the receiver. A path followed by the electromagnetic radiation from the source to the receiver is offset from the fluid exiting end of the dispense nozzle by a predetermined distance such that dispense of fluid and a major drop of fluid depending from the fluid exiting end of the dispense nozzle obstruct the path and such that a minor drop of fluid does not obstruct the path.
