Blue Sea Mini OLED Tank Level Meter - Yellow
Blue Sea Mini OLED Tank Level Meter - Yellow
High-Contrast Digital % & Bar Graph Readout - Standard 29mm Cutout

DESCRIPTION
Compact Digital Fluid Monitoring for Marine and Off-Grid Systems
Accurately tracking fluid capacities is essential when travelling off-grid or navigating coastal waters. The Blue Sea Mini OLED Tank Level Meter delivers precise, real-time monitoring of your vital onboard reservoirs within a highly compact footprint. Engineered to display both an exact percentage value and a visual level bar graph, this digital gauge eliminates the guesswork associated with traditional analogue needles. Whether you are managing potable freshwater, monitoring fuel reserves, or keeping a close eye on grey and black waste tanks, this unit provides the clarity and reliability required for demanding marine, caravan, and RV installations.
High-Contrast Visibility in Any Lighting Condition
Standard LCD screens often suffer from poor viewing angles and wash out under direct sunlight, while overly bright LEDs can ruin night vision at the helm. This digital tank gauge utilises advanced Organic Light Emitting Diode (OLED) technology, rendering a sharp, high-contrast yellow readout against a deep black background. The bright yellow screen is effortlessly legible across wide viewing angles and in bright daylight, yet remains comfortable to view during night passages or inside dark camper trailers. By providing both a numerical percentage readout and a graphic bar indicator, system operators can assess fluid statuses at a glance.
Key Features and Benefits
- Dual-Format OLED Readout: Displays tank capacity as an exact numerical percentage alongside a clear graphical bar for immediate visual reference.
- High-Contrast Yellow Display: Polarised to ensure clear visibility in harsh sunlight without causing disruptive glare in low-light environments.
- Standardised Panel Mounting: Features a convenient threaded body designed to fit a standard 1-1/8" (29mm) circular cutout, matching the size of common 12V accessory sockets.
- Splash-Proof Front Seal: Supplied with a dedicated foam sealing gasket to sit flush against the mounting surface, preventing moisture and dust ingress into the dashboard cavity.
- Space-Saving Profile: Ideal for modern helm stations, canopy control panels, and compact RV electrical cabinets where dashboard real estate is limited.
Streamlined Installation and Dashboard Integration
Retrofitting new gauges into existing dashboards or custom switch panels can often require complex cutting tools and extensive modifications. The Blue Sea Mini OLED series simplifies this process through its clever cylindrical housing. Requiring only a standard 1-1/8" (29mm) hole saw, the threaded body passes cleanly through the mounting panel and secures tightly from the rear with a locking nut. This identical sizing to standard 12V cigarette lighter sockets allows you to easily repurpose unused power outlets into dedicated fluid monitoring stations.
In marine and off-road environments, electrical components are frequently exposed to damp air, condensation, and accidental splashes. Unlike basic aftermarket displays that leave rear wiring vulnerable to the elements, this unit includes a precision-cut foam gasket. When tightened against the mounting face, it establishes a protective, splash-proof barrier that safeguards your behind-panel circuitry and reduces the risk of premature corrosion.
Versatile Applications Across Vessels and Vehicles
Designed to integrate seamlessly into professional 12V and 24V DC electrical architectures, the BS-1739 is a versatile addition to any mobile or remote setup:
- Marine Vessels: Monitor fuel tanks, freshwater bladders, or holding tanks directly from the helm or cabin distribution panel.
- Caravans and Motorhomes: Keep track of drinking water supplies and greywater capacities during extended off-grid stays.
- 4WD Canopy Fit-Outs: Integrate neatly into compact dual-battery control boxes to monitor onboard water tanks.
- Industrial and Off-Grid Equipment: Track diesel generator fuel levels or remote fluid storage tanks with digital accuracy.
