The upper and lower valves of the quick installation glass tube liquid level gauge are both chuck ferrule connectors or clamp type connectors. The ferrule and clamp welded on the container are matched and sealed to facilitate cleaning and disassembly. It forms a connector with the container and directly displays the medium level of the container through the glass tube.
Needle valves are installed at both ends of the instrument and steel balls are installed inside. When the glass tube is broken due to an accident, the steel balls will automatically close the needle valve channel under the pressure of the container to prevent the medium in the container from flowing out.
