Float & Board Level Indicator: A Robust Mechanical Solution for Tank Level Monitoring

Where the attention eye of liquid level monitoring in gigantic storage tanks—particularly where ruggedness, simplicity, and precision matter—is in play—the LiquiLevel FBS Float & Board Level Indicator by Nikeson is the best choice. The tough, mechanical gauge skillfully marries traditional float-and-pulley mechanics with an externally constructed precision readout, providing reliable performance in industrial and commercial applications.

1. How It Works: The Basics of Float-and-Board Mechanics

In the LiquiLevel FBS is a stainless steel float connected by cord and pulleys to an external indicator on an aluminum gauge board. As liquid levels within the tank rise and fall, the float rises and falls. That motion is transmitted mechanically to the display pointer, which moves freely on the gauge board (through the use of nylon roller guides). A two-wire guiding system stabilizes float movement accurately. The float is at the top for empty tank and bottom for full tank. It's a really simple, natural way of reading liquid level

2. Precision & Accuracy Built In

Though mechanically simple, the FBS is extremely accurate. With guided float operation and nylon rollers, it reads to ±5 cm (≈2 inches) with exact accuracy. Floats in various sizes are available—200 mm for tanks up to 7.5 m deep, or 350 mm floats for up to 15 m depth. Graduations are distinctly etched in inches/feet or centimeters/meters, providing consistent readings in imperial as well as metric scales

3. Built to Last: Quality Parts

From its Swedish-designed parts to its marine-grade construction, FBS is all about durability:

Gauge board: Slotted rail system made of powder-coated aluminum employs vinyl-cut graduations and stabilized by stainless-steel brackets—tough but simple to install

Float: Stainless steel construction with corrosion-proof guide lugs and braided cord

Pulleys & conduit: Galvanized or cadmium-plated steel, PTFE-bushed elbows and weatherproof housings

UV, rain, wind-proof—and even withstanding temperatures up to 150 °C in certain models.

4. Field Stacking and Simple Self-Assembly

Nikeson created the FBS in package form ready to assemble. Each gauge board comes in 1 m lengths complete with tee-nut channels and bracket sets for stacking. The package consists of:

Metric or imperial gauge boards

Tank brackets and joiners for gauge boards

Float and guide-wire tensioners

Stainless-steel float, cord, and anchor plate

Conduit piping and fasteners

It is simple to install using basic tools and can be accomplished on site—perfect for retrofitting installed tanks.

5. Cost-Effective Alternative to Electronics

Electronic level probes, sensors, or pressure transmitters are accompanied by electrical power, data wiring, and calibration software. FBS is mechanical—the lack of power, the lack of firmware bugs. With high-quality materials and virtually no consumable parts, upkeep is minimal: rare cleaning, lubricating the wires, and pulley checking. To businesses such as water treatment, firefighting, agriculture, and industrial liquid storage, this means substantial installation, operating, and trouble-shooting cost savings.

6. Versatility of Application

Versatility of application is one of the greatest strengths of the FBS. It can be used for new and retrofit installations for:

Water, rainwater harvesting, and treatment tanks

Fire-fighting water storage

Its guided float system prevents swaying or oscillation, even on turbulent or partially filled tanks, giving precise readings under various environments.

7. Seamless Integration and Modularity

Gauge boards are accessed just through the use of M6 tee nuts, with adjustable height up to 15 m or more. Brackets, which are mounted at each 1 m spacing, provide alignment, while conduit piping shields moving parts and cord. The visual marker is red powder-coated for maximum visibility—even from a distance. Metric or imperial, vertical or horizontal controllers—it all gets along nicely

8. Reliability Meets Peace of Mind

What distinguishes the FBS is its electricity-zero-dependency. No need to replace batteries, no fear of electrical failure, no calibration drift. The system works where electrical availability is restricted or environmentally demanding. And with a lifetime-warranty on the indicator unit, owners have long-term assurance and operation ease.

Final Thoughts

For companies seeking easy-to-keep-in-wrong, precise, dependable tank-level gauges, the LiquiLevel FBS Float & Board Level Indicator is a tried-and-tested, value-priced solution. Its mechanical superiority, stainless steel durability, modularity, and straightforwardness guarantee that it is the right choice for water tanks, fire protection systems, industrial tanks, and chemical tanks. For new installations or retrofits, the FBS offers continuous, day-in, day-out reliability—no batteries, no software, no hassle.
