  • AIR BUBBLE DETECTOR
    Publication number: 20250198938
    Abstract: An air bubble detector including a case and an optical detection module, the case has a first side, a second side and a tunnel with a first opening at the first side and a second opening at the second side. The optical detection module is provided in the case and communicated with the tunnel. A hose is received in the tunnel of the case via the first opening, and the optical detection module senses optical signals of fluid in the hose for determination of air bubbles in the fluid.
