A Float and Board Type Level Indicator is a simple, reliable, and cost-effective mechanical device used for continuous liquid level indication in storage tanks, process vessels, overhead tanks, underground tanks, and reservoirs. The system operates on the principle of buoyancy, where a float rests on the liquid surface and moves up or down according to changes in the liquid level. This movement is transmitted through a wire rope and pulley mechanism to a counterweight and indicator board, providing a clear visual representation of the liquid level.

Widely used in water treatment plants, chemical industries, power plants, oil terminals, refineries, and process industries, Float and Board Type Level Indicators offer accurate level monitoring without requiring any electrical power supply. Their rugged construction and simple operating mechanism make them ideal for outdoor and industrial applications where reliability and ease of maintenance are essential.

Designed for large tanks and reservoirs, these indicators provide excellent visibility from long distances, enabling operators to monitor tank levels safely and efficiently.
