Victron GX Tank 140

The GX Tank 140 is a tank level monitoring interface designed for use with Victron GX devices. It converts resistive tank sender signals into data readable on the GX system, allowing fuel, water, waste water and other fluid levels to be monitored remotely via the Victron ecosystem. It is suited to marine, off-grid and mobile installations where tank level visibility is required alongside other system data.

Key Features

• Connects resistive tank level senders to any Victron GX device via the VE.Can (CAN-bus) network.
• Supports sender resistance ranges of 0 to 180 ohms and 180 to 0 ohms, covering the most common marine and automotive sender standards.
• Tank level data is displayed on the GX device touchscreen, the VRM portal and the Victron Connect app.
• Compact and lightweight at 0.1 kg, suitable for installation in confined spaces typical of marine and vehicle builds.
• Multiple GX Tank 140 units can be connected to a single GX device over the VE.Can bus, enabling monitoring of several tanks simultaneously.
• Tank type is configurable in the GX device settings: fuel, fresh water, waste water, live well, oil, black water and more.

Product Overview

The GX Tank 140 sits between a conventional resistive tank sender and the VE.Can bus on a Victron GX system. Rather than requiring a dedicated analogue gauge, it digitises the sender signal and passes it to the GX device as structured data. This means tank levels appear alongside battery state, inverter status and solar yield in a single monitoring interface, whether that is a Cerbo GX, Venus GX or compatible equivalent.

The unit supports the two most widely used resistive sender ranges, making it compatible with the majority of senders found on boats, motorhomes and off-grid installations. Configuration is handled entirely within the GX device menus, so no additional software or tools are required during commissioning. Because the GX Tank 140 communicates over VE.Can, the bus address is assigned automatically and multiple units can be daisy-chained without conflict.

Tank level data logged through the GX device is also available on the VRM online portal, providing historical trend data and remote visibility for fleet operators or system managers monitoring installations from a distance.

Installation Notes

The GX Tank 140 requires connection to a VE.Can network and a compatible Victron GX device. Wiring to the tank sender and CAN-bus termination should be carried out by a qualified marine electrician or experienced system installer. Ensure the VE.Can bus is correctly terminated at both ends with 120-ohm resistors as required by the CAN-bus standard. Verify sender resistance range compatibility before installation to avoid inaccurate readings.
