  • High accuracy liquid density sensor
    Patent number: 9222868
    Abstract: A liquid density sensor has a sensing module, a sensing rod and a floating device. The sensing module has a control circuit having computing functions. The sensing rod has a sensing line electrically connected to the control circuit. The floating device has a first magnetic unit and a floating ball mounted therein. The sensing rod is mounted through the floating device and the floating ball. The floating ball has a second magnetic unit. A specific gravity of the floating ball is lower than that of the floating device. The control circuit calculates a liquid density of liquid based on a distance between the first magnetic unit and the second magnetic unit according to a linear formula.
