STRUCTURE AND MEASUREMENT PRINCIPLE
The HSG dual color glass tube level gauge utilizes optical principles to display the height of the liquid level in color through natural light.
The liquid level gauge consists of colored glass tube, sheath, upper and lower needle valves, connecting flanges or threads, and other components. Form a connector with the container and directly observe the height of the liquid level through a glass tube.
The upper and lower needle valves are equipped with steel balls. When the glass tube accidentally breaks, the steel balls quickly block the channel to prevent the medium from spraying out.
The HSG-TB type enamel glass tube level gauge has strong corrosion resistance and does not contaminate the measured medium. It can be used in industries such as pharmaceuticals.
