Abstract: A fluid detection flange for a product transfer verification system includes a coupling frame having an opening defining a fluid path configured to be fluidly coupled with a fluid source. A sensor in the flange measures at least one characteristic of a fluid in the opening and the sensed characteristic is used to determine the type of fluid pending for transfer. In operation, if the pending fluid is the same type as is meant to be placed in a destination container then the transfer is allowed.

Abstract: A vaporizer including a reservoir for storing an anesthetic liquid agent and a vaporizing element configured to vaporize the anesthetic liquid agent. A level detector is located outside of and adjacent to the exterior of the reservoir. The level detector includes at least one electrical field sensor configured to provide an output voltage signal based upon the capacitance of material within the reservoir proximate the electrical field sensor. The vaporizer includes a display providing a visual indication of the amount of liquid anesthetic agent in the reservoir.
