The working principle of UHM-D (top mounted) flip column level gauge is a product that displays the liquid level in the buried storage tank on the ground indicator by lifting the rod; The floating ball moves up and down along with the liquid level in the pipeline or guide frame inside the tank, driving the magnet inside the main tube to move up and down, causing the flipping column (which is composed of red and white colors) to flip 180 degrees, resulting in the flipping column display showing white on the upper part and red on the lower part.  

UHM-D (top mounted) flip column level gauge can also be combined with a magnetic switch to form a top mounted flip column control level gauge; Cooperate with bundled transmitters to form a top mounted flip column remote liquid level gauge. The flange (reserved hole) for the installation port of this type of liquid level gauge storage tank should not be less than DN80. It is recommended that you reserve a DN100 interface flange.
