  • Capacitive fluid level detector
    Patent number: 11898891
    Abstract: A fluid level detector is provided, which has a transmitter, a receiver, and a sensing zone adjacent the transmitter and receiver. The transmitter and receiver are arranged such that when an electric field forms between the transmitter and receiver, a fringe electric field extends from the transmitter into the sensing zone. The transmitter and receiver are both on a same side of the sensing zone, and a fluid located at the sensing zone changes a measured capacitance at the transmitter and receiver system.
    Type: Grant
    Filed: March 7, 2023
    Date of Patent: February 13, 2024
    Assignee: BE THE CHANGE LABS, INC.
    Inventors: Wouter Konings, Allen Simon, Stijn Kroeze, Ad van den Bemt
