KUS Marine Fuel Level Gauge – 52 mm, 12/24V (Black/White)

This marine fuel level gauge by KUS provides accurate and timely information about the amount of fuel in your tank. With a size of Ø52 mm, the gauge fits easily into your boat’s instrument panel – this is the standard size for most marine instruments, making its integration seamless. The gauge is designed to operate on both 12-volt and 24-volt electrical systems, so it’s compatible with a wide range of vessels – from small motorboats to large yachts. Its IP67 waterproof rating means the gauge is protected against water ingress even when submerged up to 1 m for 30 minutes – rain, waves, or high humidity will not affect its operation. The special glass on the display is treated to prevent fogging, which stops condensation from forming during rapid changes in temperature or humidity. Additionally, the glass is scratch-resistant, keeping it clear over time despite cleaning or accidental contact with sharp objects. The KUS gauge features an analog dial with clear markings (E – 1/2 – F) and colored backlighting (red or yellow, depending on model), which makes it easy to read both by day and at night.

• Wide Compatibility: The instrument works with all standard float-type fuel senders using the 10 Ω (Empty) to 180 Ω (Full) range, which is widely used in Europe. This allows for easy connection to an existing in-tank sensor without requiring a replacement. (If needed, it can be configured for other ranges or the US standard 240–33 Ω, per manufacturer instructions.)
• Marine-Grade Durability: The gauge’s rear casing is plastic and corrosion-proof, and the front (especially on the white version) has a bezel made of stainless steel (AISI 316), ensuring a long lifespan even with constant salt spray exposure. The internal electronics are designed to withstand the vibrations and shocks typical on boats.
• Ease of Monitoring: The bright LED backlight evenly illuminates the dial, which is especially useful during night voyages or in low-light conditions. In daylight, the anti-glare glass provides good contrast, so you can read the fuel level at a glance. This means less time with the captain’s eyes off the course and more confidence in the remaining fuel.
• Enhanced Safety: Continuously monitoring fuel level is key to avoiding an unexpected outage far from shore. With this gauge, you can plan refueling with precision and avoid risky situations. Additionally, the needle on this gauge doesn’t “bounce” – it’s damped to provide a steady reading even in rough seas, preventing misinterpretation of the fuel status.
