NISAN offer Float & Board Type Tank Level gauge (indicator) suitable for large non – pressurized liquid storage tanks / vessels. This gauge is also applicable to cone roof, float roof, floating roof, under grand tanks etc. The Specific Gravity of the fluid should be more than 0.6(Free Flow) This level gauge wonks on the principle of buoyancy. The whole unit consist of two types of parts. Viz wetted parts & non-wetted parts. Wetted parts are those which come in contact with the liquid e.g., Float anchor plan float guide wire etc while. Nonwetted parts are the one which do not come in contact with the liquid e.g., Float wire, Mountain Breakers indicator pulley pulley hosing scale, indicator etc. The Float is available in different material S.S.304 / S.S.316/P.P./Teflon etc. 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 5 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. Float Inside the tank raises and deals with the level of fluid this makes the pointer move on the scale indicating level inside the tank. 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.

NISAN also offers vapour Seal Type float & Board type level Gauge which is generally used for tanks having corrosive fumes / vapours OR N2 [Nitrogen] Purging tanks. In this level gauge the float is connected to a magnetized counterweight moving in a sealed S.S. pipe & which drive drives a follower magnetized bi - colour capsule inside a glass tube to indicate liquid level.
