  • Patent number: 10551238
    Abstract: An ultrasonic sensor for detecting the presence or absence of an aerated fluid includes a probe having a first solid portion and a second hollow portion. The probe has a closed end at the hollow portion. The solid portion and the hollow portion define an interface therebetween. A transducer element is mounted to the probe at about the solid portion. The transducer element is configured to transmit an ultrasonic signal through the solid portion into the hollow portion and to receive reflections of the ultrasonic signal to determine the presence or absence of a fluid and/or an aerated fluid.

  • Patent number: 9121746
    Abstract: An ultrasonic liquid-height detector employs conductive rods extending from a housing, and corresponding transducers, into a liquid, where elastic seals surround the rods at their exit point from the housing. Acoustic crosstalk between the rods through the seals and the housing (rather than through the liquid) is minimized by displacing the seals from each other as measured through the housing to increase a path length through the housing so that the crosstalk energy is delayed with respect to the direct energy indicating liquid height. A sampling window is positioned to sample transmitted sound across the rods at a time before the arrival of the crosstalk energy.

  • Patent number: 8646328
    Abstract: A level sensor for determining the presence or absence of a liquid in contact with the sensor includes an elongate probe, a transducer operably connected to the probe and configured to produce compressional waves in the probe, and circuitry for detecting acoustic energy emitted into the liquid when liquid is in contact with the probe. A mount for the releasably holding the sensor includes a base have a receiving region formed in part by a plurality of flexible securing fingers. The fingers have locking projections extending therefrom. A contact is mounted to the base and extends into the receiving region. A cartridge supports the level sensor and is received in the receiving region. The cartridge includes a circumferential recess for receiving the securing fingers. When the level sensor is positioned in the cartridge and the cartridge is inserted into the base, the level sensor is operably connected to the contact and the cartridge is resiliently secured in the base.
