초록 ▼

A volume sensing system includes electronic circuitry which is electrically connected to an ultrasonic transducer. The transducer is affixed by means of an adaptor to the base of a container having a known configuration. The container holds a liquid and a gas so that a liquid-gas boundary is formed within the container. The transducer generates ultrasonic pulses which propagate through the liquid, are reflected at the liquid-gas boundary, and are received again by the transducer. The received return pulse is converted into an electrical signal which is analyzed by the electronic circuitry to determine the level of the liquid within the container. The level of the liquid within the container is then employed to determine the volume of the liquid within the container in accordance with the configuration of the container. In a preferred embodiment, the adaptor includes an indicator which may be used to identify the configuration of the container.

대표청구항 ▼

An adaptor for providing an interface between a container having a predetermined configuration and a transducer for generating an ultrasonic pulse, wherein: said adaptor is formed to affix to said container of said predetermined configuration and to said transducer so that said adaptor may be used only to connect said container and said transducer, said transducer being in sonic communication with said container when said transducer is affixed to said container by way of said adaptor, wherein said transducer generates an ultrasonic signal through said liquid in order to measure the volume of said liquid in said container; and said adaptor includes an indicator which identifies said configuration of said container to which said adaptor connects, said indicator including circuitry which is capable of transmitting data for identifying said adaptor and said predetermined configuration of said container.
