Description

Buy the Victron Energy GX Tank 140 now for just $49.30 — a 50% discount off $98.60. It is the best-fit accessory for RV, boat and off-grid owners using a Victron Cerbo GX who want consolidated tank level monitoring for up to four tanks.

Connecting 4-20mA and 0-10V Senders

The GX Tank 140 supports current senders (4–20mA) and voltage senders (0–10V). Two of the four inputs supply 24V to power the sender; the other two channels require an external power supply, with a power-in terminal and fused outputs provided. Configure upper and lower limits in the GX device to match senders that only cover part of the scale, such as 0–5V.

Four tanks, one screen

Fresh, gray, black, and diesel all visible on my Cerbo GX at a glance. Setup was painless with my 4-20mA senders. Finally no more sticking a flashlight in the tank hatch.

Great addition to the GX ecosystem

Integrates seamlessly with my Cerbo and the VRM portal shows tank levels remotely. Calibration took some trial and error with my resistive-to-current converter. Once dialed in, readings are accurate and stable.

Works perfectly

Accurate readings, easy setup, solid build.

Good but documentation is thin

The hardware is quality Victron gear, no complaints there. Wiring diagrams in the manual assume more expertise than I have, so I needed forum help. Now that it's installed, it works flawlessly. Docking a couple stars for the setup experience.

No more overflow surprises

My wife once left the water filling with the hose running — never again. Alarm thresholds on the Cerbo notify us when the black tank nears full. Install in the compartment took under an hour. This little box has saved us from at least one very bad day already.
