Victron GX Tank 140

The GX Tank 140 is a tank-level monitoring accessory for Victron's GX system range, most commonly paired with the Cerbo GX. It reads up to four tank level sensors and displays levels locally on the GX device or remotely through the VRM Portal, giving you fuel, fresh water, grey water, and waste tank visibility from anywhere.

Key Specs:

• Inputs: Up to 4 tank level sensors
• Sender Compatibility: Current senders (4-20 mA) and voltage senders (0-10V)
• Connection: USB to GX Device (also powers the unit — no separate power wiring needed)
• Sender Power: 2 of 4 inputs provide 24V power to the sender; remaining 2 channels require external power (with power-in terminal and fused outputs)
• Configurable Range: Upper/lower limits adjustable for partial-scale senders (e.g. 0-5V)
• Damping: Configurable 1-60 seconds for stable readings
• Fault Detection: Alarms on out-of-range values from faulty sensors or wiring

For marine applications, a GX Device can broadcast these tank levels over NMEA 2000 so they show up on other displays such as a multifunction display (MFD).
