The Victron GX Tank 140 reads up to four tank level sensors and displays the levels on a compatible GX device, such as the Cerbo GX, or remotely through the VRM Portal.
It works with current senders (4 to 20 mA) and voltage senders (0 to 10 V). The unit connects to the GX device over USB, which also powers it, so no separate power wiring is needed for that connection.
Two of the four sender inputs provide a 24 V power supply for the sender. The other two channels need an external power supply, with a power-in terminal and fused outputs provided for that purpose. Upper and lower limits are configurable to work with senders that only cover part of the scale, and reading damping can be set between 1 and 60 seconds for a stable readout. The GX Tank 140 also detects faulty sensors and wiring issues and raises an alarm when values are out of range.
