Precision Fresh Water Tank Monitoring for Caravans, RVs, and Marine Applications

Real-Time Digital Level Indication with Continuous LED Bar Display

The Votronic Tank Level Display S provides accurate, real-time monitoring of your fresh water reserves, engineered for mobile and off-grid environments. Designed and manufactured in Germany, this panel-mounted indicator works with the Votronic electrode sensor (sold separately) to deliver precise level measurement across any tank material or size. The 10-segment LED bar illuminates in three colours, showing fill levels from 10% to 100% with intermediate brightness for partial states, so you can assess your water supply at a glance without guesswork.

Unlike basic float switches or generic gauge panels that offer only coarse readings, the Votronic system continuously tracks the water column, updating the display in real time during filling and draining. This immediate feedback helps prevent overflows, dry pump operation, and unexpected shortages, reducing the risk of water damage and equipment strain.

Compact Design with Minimal Mounting Depth

With a front panel measuring just 47 x 85 mm and a mounting depth of only 15 mm, this display fits into tight spaces where behind-panel clearance is limited. The shallow recessed installation preserves storage compartments and allows flexible placement in control panels, cabinetry, or dashboards. Four corner screw points secure the unit firmly, and the supplied fastening hardware simplifies retrofitting into existing setups.

Key Features

• 10-LED bar graph with three-colour indication for quick visual reference
• Continuous measurement with variable brightness for intermediate levels
• Compatible with 12V and 24V DC systems, drawing only 1–30 mA
• Automatic shut-off after approximately 10 minutes to conserve battery power

• Fresh water symbol clearly identifies the unit for dedicated tank monitoring

Reliable Operation in Mobile Environments

The Votronic display is built to withstand the vibrations, temperature swings, and electrical noise common in caravans, motorhomes, and boats. Its low current consumption makes it suitable for extended off-grid use, while the automatic power-down feature prevents unnecessary battery drain. The front panel markings remain legible under varying light conditions, and the LED brightness adapts to ambient levels for comfortable viewing day or night.

Seamless Integration with Votronic Modular System

This fresh water display shares the 85 mm height of other Votronic panel instruments, creating a uniform appearance when multiple units are installed side by side. Whether you are monitoring a single tank or building a comprehensive control panel for fresh, grey, and black water levels, the consistent styling and straightforward wiring simplify installation and enhance the professional look of your vehicle or vessel.
