Victron GX Tank 140 – Voltage Sensor for Tank Level Monitoring

The GX Tank 140 takes readings from up to four voltage sensing tank level monitors. It is used in conjunction with the Cerbo GX advanced system monitor or other GX-enabled devices. Whether you are looking to monitor your fresh water, grey water or fuel tank if your tank sensor uses voltage to infer the level of fluid in the tank you will need a GX Tank 140. Please note: If you connect a voltage-based sensor directly to the Cerbo GX this will permanently damage the analogue input.  

Tank levels can be displayed either through a GX Touch screen or remotely through the VRM Portal. You can see our van’s tank levels in our live VRM system here.

The GX Tank 140 is compatible with current senders (4 to 20 mA) as well as voltage senders (0 to 10 V). The connection to the GX Device is via USB, which is also how the GX Tank is powered. To keep the tank sender wiring is kept as simple as possible: two of the four inputs provide a 24 V power supply, to power the sender. The other two channels do require an external power supply, and there is a power-in terminal together with fused outputs to facilitate that. 

Upper and lower limits are configurable, to allow using senders that provide only part of the scale, for example 0 to 5 V.

To provide a stable reading, the readings are averaged over an editable time period to dampen the effect of fluid movement. The damping can be configured between 1 and 60 seconds. If a sensor becomes faulty or a wiring issue is detected, an alarm will be raised when values are out of range.

For marine applications, the GX Device can transmit these tank levels on the NMEA 2000 network to be picked up by other displays such as an MFD.
