  • LIQUID LEVEL DETECTING APPARATUS AND METHOD
    Publication number: 20180283915
    Abstract: A liquid level detecting apparatus comprises: a container (10), a partition plate (110), a first electrode pair (120), a second electrode pair (130), and a master chip (210). The partition plate (110) dividing the container (10) into a first containing chamber (101) and a second containing chamber (103). The master chip (210) is electrically coupled to the first electrode pair (120) and the second electrode pair (130), respectively, which is configured to measure a first voltage value Uf of the first electrode pair (120) and a second voltage value Ux of the second electrode pair (130) and calculates a height Hx of the conductive liquid of the second containing chamber (103).
