Victron CerboGX tank level sensor

Water

Hi All

I am looking to monitor tank levels (JoJo for drinking water).

Where can I find a sensor compatible with the CerboGX tank sensor input?

Thanks
Mark

Maybe one of these will suit?
(I have no experience with them).

Thanks Phil

Was looking at similar to this but in SA and CHEAPER :wink:

That sensor isn’t directly compatible with the Cerbo. The Cerbo only supports resistive sensors that output between 0-180 Ohm (EU models) 230-30 Ohm (US) that are typically used in fuel tanks. (You can see the one @Phil.g00 listed is quite small relative to a Jojo tank.)

If you want to use a voltage-level sensor, like the one you listed, you’ll need an adapter that seems to be pretty scarce, or you can use the official GX Tank 140 - Victron Energy USB accessory:

  • Interfaces with either 4 to 20mA or 0 to 10V tank level sensors (including a combination of both).
  • Configurable input range, for example to connect a 0 to 5V sensor.

0-10V & 4-20ma sensors are typically used for water storage tanks (on land).

Thanks Marius!!

I have looked at the Tank 140 but only need 1 sensor for all my tanks - they are on the same level so equalise - trying to find a cheaper solution.

If you’re only looking for IS_FULL and IS_EMPTY, you can maybe just use the really cheap sensors top & bottom wired to a digital input?

I want to see the full range so Tank 140 may the only option…

Hmm, I’m thinking one of those “tank” sensors might work pretty well for a pool… The range above and below the weir is the only part you really care about :slight_smile:
