  • Patent number: 7694560
    Abstract: Apparatus for measuring the level of liquid in a container has a substrate on which a plurality of piezoelectric elements are mounted that are to transmit ultrasonic energy upwardly through the bottom of a container placed on and supported by the substrate into the container and to receive ultrasonic energy reflected back from the liquid/air interface within the container from which the round trip time can be measured and the liquid level calculated. The plurality of piezoelectric elements are of predetermined shapes and mounted spaced apart on the substrate in an array to accommodate containers with different shape bottoms.

  • Patent number: 7694570
    Abstract: A non-invasive dry coupled disposable/reusable ultrasonic sensor has a housing and a piezoelectric element at one end of the housing to which connected signal leads are connected that extend out from the housing. A piece of double-sided adhesive tape has one adhesive side secured directly to the face at the one end of the housing with the other adhesive side to be secured directly to the outer surface of a pipe or vessel. The tape can cover the entire face of the one end of the housing or only that part that the piezoelectric element faces.
