In this level gauge, the float is design as per the specific gravity of the liquid, floating on the liquid levels. This float connected to a pointer through Rope via a Sets of Pulleys, The pointer slides over a CM marked Board, Installed Parallel to the tank. For more than 3 metre height of the tank we provide two guide wires firmly anchored to the tank bottom. So that horizontal movement of the float is restricted. In this level gauge, when tank is full the pointer is at bottom position on board and when tank is empty, the pointer will be at top position
