Precision Black Water Tank Monitoring for Mobile and Marine Applications

Reliable Level Sensing for Faeces and Toilet Waste Tanks

The Votronic Tank Level Display S for black water delivers accurate, real-time monitoring of faeces and toilet waste tanks in caravans, motorhomes, and marine vessels. Engineered in Germany, this display works with Votronic tank sensors to provide continuous level measurement, eliminating guesswork and preventing overfill incidents. Its clear 10-segment LED bar with three-colour indication allows instant visual assessment of tank capacity from 10% to 100%, even in low-light conditions.

Unlike basic float switches or generic indicators, the Votronic system uses advanced electrode-based sensing suitable for any tank material and size. This ensures consistent readings regardless of tank geometry or waste composition, reducing the risk of sensor fouling common in black water applications. The display’s continuous operation means you see real-time changes during filling and emptying, giving complete control over waste management.

Designed for Demanding Mobile Environments

With a mounting depth of only 18 mm and compact front panel dimensions of 85 x 47 mm, this display fits almost anywhere without sacrificing valuable storage space behind the panel. It integrates seamlessly into the Votronic modular system, matching other displays in height and style for a cohesive dashboard appearance. The unit operates across a wide voltage range of 10 V to 32 V, making it suitable for both 12 V and 24 V DC systems commonly found in recreational vehicles and boats.

Installation is straightforward with corner mounting holes and screw terminals rated for 0.5 Nm torque. The display can be switched on or off manually, or it will automatically power down after approximately 10 minutes to conserve battery power. A switching output provides up to 120 mA for controlling external devices like pumps or alarms, adding functional versatility.

Why Choose Votronic for Black Water Monitoring?

Black water tanks present unique challenges: corrosive waste, sludge buildup, and unreliable sensor readings. The Votronic system addresses these with electrode sensors that resist fouling and provide accurate data regardless of tank material—plastic, metal, or fibreglass. This reduces the risk of unexpected overflows or false empty readings that can lead to unsanitary conditions and costly cleanup.

For caravan and motorhome owners, knowing the exact toilet tank level means better trip planning and fewer stops at dump points. Marine users benefit from compliance with environmental regulations by preventing accidental discharge. The display’s clear toilet tank icon and percentage scale eliminate confusion, ensuring that even in multi-tank setups, the black water status is unmistakable.

Seamless Integration with Votronic Modular System

This display is part of the Votronic S series, designed to work with matching fresh water and grey water displays for a complete tank monitoring solution. All units share the same 85 mm height and panel-mount design, allowing a uniform dashboard layout. Retrofitting a single display is simple, and the system can be expanded as needs grow. The low current consumption (1 to 30 mA) minimises impact on battery banks, a critical factor for off-grid setups.
