Professional tank level monitoring solution
The Victron Energy GX Tank module provides a reliable and accurate solution for continuous monitoring of water tanks, sewage tanks, and other liquid tanks. Ideal for RVs, boats, off-grid systems, vacation homes, and industrial applications where knowledge of water supply and tank levels is crucial.
Main features and benefits
- Simultaneous measurement of multiple tank levels (water, gray water, black water, fuel).
- Continuous level measurement with percentage or liter display.
- Accurate and stable signal conversion from various level sensors.
- Full integration with GX monitoring systems and VRM online portal.
- Real-time monitoring locally, remotely, or via mobile app.
- Configurable alerts for low or high tank levels.
Applications
The tank level monitoring module can be effectively used in various areas where reliable measurement of water or other liquid levels is important:
- Freshwater, gray water, and sewage tanks in RVs and caravans.
- Water and fuel tanks in sailing boats and motor yachts.
- Water storage and buffer tanks in off-grid solar systems.
- Rural properties, wells, cisterns, and rainwater collection systems.
- Monitoring tank levels of smaller industrial tanks, process water, or chemical tanks.
Compatibility with level sensors
The module can work with various tank level sensors, making it easy to integrate into existing systems. The most commonly used transmitters are:
- Resistive level sensors (e.g., 0–180 Ω or 240–33 Ω standards).
- Voltage output transmitters (e.g., 0–10 V).
- Current loop-based transmitters (4–20 mA, with appropriate interface).
The inputs can be configured, allowing the module to adapt to different scales and convert the liquid level to percentage values or volume expressed in liters.
Integration with GX systems and online monitoring
The tank module is fully integrable into the Victron GX family (e.g., Cerbo GX, Color Control GX, Venus OS-based devices), so the tank level data appears:
- on the local display or touchscreen,
- through a web interface,
- on the VRM portal providing remote monitoring.
This allows for checking water and fuel supplies from anywhere and responding timely to events such as low water levels or overflow risks.
Liquid level measurement and calibration
One of the key features of the module is flexible calibration. Tank shapes are rarely completely regular (e.g., not perfect rectangular), so the relationship between level and volume is not always linear. During setup, the following can be defined:
- The nominal volume of the tank in liters.
- The minimum and maximum values of the level sensor signal.
- Custom calibration points for accurate volume calculation.
Through calibration, the displayed liter data and percentage fill closely approximate the actual tank volume, which is crucial for water and liquid management.
Alerts and automation options
The system can handle various level-related alerts. It can be set to send notifications below or above certain fill levels:
- In case of low freshwater level.
- When the sewage or wastewater tank is full.
- At critically low fuel levels.
Alerts can appear on the local display, via email, or as push notifications, depending on the settings of the GX system and VRM. Additionally, in more advanced systems, the received information can be used to trigger automated processes, such as starting or stopping a pump.
Reliability and durability
Components manufactured by Victron are well known for their reliability, especially in off-grid and mobile applications. The tank level monitoring module:
- provides stable operation even under extreme conditions,
- is capable of consistently accurate measurements over the long term,
- integrates with existing Victron system components.
Why is tank level monitoring useful?
Proper tank management is essential for safe operation and convenience. Accurate liquid level measurement helps:
- avoid unexpected water shortages while traveling,
- prevent sewage tank overflow,
- optimize water usage in off-grid environments,
- track fuel consumption,
- plan refueling and emptying more efficiently.
Summary
The GX Tank module provides transparent, reliable, and flexible tank level monitoring for any system where continuous tracking of water or other liquid levels is critically important. Its compatibility with various level sensors, GX centers, and the online VRM monitoring platform results in a comprehensive solution that serves convenience, safety, and efficient resource management.
