Cerbo GX Sensor Recommendations

I'm super excited to find that Cerbo GX can monitor my batteries, solar, AND tanks. My stock KIB sensors are nearly useless, reading 2/3 full until gray water starts coming up my drain, signaling 100% full. It's pathetic.

Does anyone know what sensors I can use that will give accurate level readings and work with Cerbo GX / GX Touch? I would like fresh, gray, black, and propane sensors that work with Cerbo GX.

Will this work? Do I really need 4 sensors for just the black tank?!? https://www.etrailer.com/dept-pg-RV_Sewer-pt-Probe_Sensors.aspx

Looking for input - 4 to 20mA and 0 to 10V senders

Hello Community!

We’re considering to add a USB accessory to our GX product range, to add 0 to 10V, as well 4 to 20mA inputs.

But since all of us have very limited experience with 4 to 20mA tank senders, we're looking for some input:

  1. Is it always 4mA = tank empty, and 20mA is tank is full? Or do the empty and full levels need to be configurable in a software setting on the GX Device?
  2. And how important is it that the transducer can be powered by our device?
  3. Anything else we should keep in mind when designing a 4 to 20mA input? Good features you have seen else where?

Also, if you are using 4 to 20 mA senders, please post a link to a datasheet or specs below. And if you have an opinion on the sender, what you like/don't like, welcome to add that.

Lastly, most questions above are for 4 to 20mA, not for 0 to 10V - but if you have special comments about 0 to 10V, welcome as well - obviously. The product we have in mind will have inputs that can be used for both types.


Note, that this is quite early in the product development, I can’t say anything for now with regards to availability dates.


All the best and thank you! Matthijs


ps. just to prevent any question about this: we'll soon launch a new Venus OS version that can work with irregular tank shapes, as well as naming tanks and some more features: all those features will also available for the 0 to 10V and 4 to 20mA inputs. Details here.

Can RV resistance tank sensor be used by the VEnus GX? (recreational Vehicle)

My RV has tank level sensors. 4 pins installed on tank. Each has a resistor connected to it. (except for common)

the bottom 2 pins are at same level. The current system uses 12vdc and it will read 8 vdc when they are both wet. The next pin up is 2/3 level and drop to 6vdc, and 4th pin drops to 4vdc.

So if I remove power and just use the resistances. I should be able to get some reading either NA standard or EU?

the bottom 2 pins have a 0 ohm value when jumped. @ 1/3 level

the next has a 68 ohm valve when jumped to common.

top sensor pin is 188ohm when jumped to common.


I believe this should give 256 ohm when full. and 0 when 1/3 or just slightly off 0 ohm.

I've seen many ppl ask about camper style tank sensors and I think this is what most are referring to. There is no way I can get to my tanks to install float style sensors. And if its any more than building a resistor pack to change the values. I would just stay with the original KIB Tank Monitor system.

It sure would be nice to have it all in the same display.

(Currently have venus/multiplus/bmv-712/mppt 100/50- venus is temporary until cerbo arrives in Canada in August from what I'm told)

Getting Tank Output in remote console System View

Hi, I've just installed a tank sender for the diesel tank into my Venus GX and a little disappointed to find that the only page that seems to give the output is the Boat/Motorhome overview page. There is plenty of space on the system page, so think that this info not being output there is a real shame. Let me know if I'm missing something, but I've been through all the settings and doesn't seem possible.

RV-C CAN Bus tank monitors

I'm trying to figure out how to take advantage of the tank monitoring capabilities in the CCGX. I know for resistive sending units I need the VE.Can resistive tank sender adapter... My only problem is I have three tanks (Fresh, grey, and black) and these adapters cost $400 each!!! I would end up spending more than twice as much on these "adapters" as I have invested in the CCGX itself.


So I started looking at options. For RV holding tank monitoring: SeeLevel II is pretty much considered the standard for high end monitoring. When i was looking at their product offerings I noticed they have sending units that support "RV-C" which is a CAN Bus based protocol. Since the VE.Can adapter simply converts the resistance it gets from the tank into CAN Bus messages... If the SeeLevel II sends CAN Bus messages to begin with then it *should* be fairly straightforward to just connect these to my existing VE Can bus (I already have a CAN bus between the CCGX and my Orion Lithum BMS system)


That's assuming that the RV-C messages sent by the SeeLevel II are compatible with whatever message format the VE.Can adapter sends. I'm hoping someone from Victron can help me out.

Venus GX tank sensor custom name

Hi there, I have two tank sensors connected to the Venus GX (most recent FW version 2.32). I am programming some logic with Node-Red. The Tank Sensor node tells me: "Multiple tank sensors were found with the same name. You can set a custom name for the device in Venus settings."

I looked through all the venus settings pages via Console on LAN - but nowhere found an option to change the device names of "Generic Tank Input (1)" or "... (2)".

Somebody has an advice?

Tank level sensor for deep water tanks - Venus GX

Hi,


I'm using a Venus GX and would like to incorporate tank level sensors for our domestic water tanks. The tanks are around 2.5m deep and I would like to be able to use the tank level sensor input of the Venus GX to determine the volume inside the tanks. I've not come across any sensors that can cope with this depth. Does anyone have any options?


Thanks everyone.

Tank level sensor update interval is too slow on Venux GX

I have a resistive tank level sensor (similar in design to this one) installed in a header tank, and connected to a Venus GX. It works fine so long as the tank level is relatively static - however, if the tank level is rapidly rising or lowering, the Venus can't seem to keep up.

So for example, if I turn on the pump to fill the header tank, it is overflowing by the time the Venus is even reading 80%. Once I turn the pump off, the Venus reading continues to tick upwards gradually until finally reaching 100%, but this seems to take a few minutes to catch up.

Because I want to use this reading to control the pump, it is obviously an issue. I'm fairly sure it's not the sensor, since connecting a multimeter and actuating the slide manually seems to produce instantaneous change in the resistance reading. Is there a way to get the Venus to update the reading more rapidly?

I have a CCGX running 2.31 that no longer sees my tank sensors.

The CCGX has worked well for about a year working in a marine environment.

I have 4 liquid tank senders (3 water tanks and 1 diesel tank) that are connected to the CAN network through Navico 000-11518-001.

The 3 water tanks used to display on the CCGX and VRM portal, though it never displayed the fuel tank level.

All the tanks display on the boats MFD displays ( B&G Zeus2 running 16.3 release 2)


A couple of weeks ago I had the opportunity to calibrate the fuel tank sender which I had never done before.

After the calibration the CCGX stopped reporting the water tank fluid levels, but the other displays still report all 4 tank levels.

All the other monitoring sees to still work.


The CCGX sees the three water sensors on the CAN network. And nothing thinks there are any CAN bus problems.

I have restarted everything, and done just about everything I can think of to get the sensors back on the logging system - but to no avail.


I would happily take any suggestions.

CCGX and PGN 127505 (tank level)

I have a CCGX and a Maretron 6-channel tank level sensor. The sensor issues PGN127505 level readings which are completely ignored by the CCGX.

A couple of years ago on the old discussion board I was told that the issue was that the CCGX was strictly checking the NMEA registration of the Maretron device and rejecting data from it. The implication then was that the "issue" was scheduled for a fix.

24 months have elapsed and I still can't see tank levels on the Color Control. Any further information or suggestions for a fix would be really welcome.

Venus GX tank measurement

On my boat, I have a Venus GX, and I thought it would be nifty to use it to survey the tanks (1 fuel, 2 water) as well. There are already tank meters on the tanks, which are hooked up to a shared analog gauge. I have measured the fuel tank meter, which shows 180 ohm when the tank is full. However, there is a resistor of sorts on the gauge, which shows about 150 ohm, hence the combined resistance is 82 ohm. Consequently, when hooking up the VGX to this setup, it says that the tank is about 45% full.

The obvious fix would be to disconnect the analog gauge, but I would certainly prefer to keep it as well. Is there a way to resolve this?


Thanks,


Eirik

Tank Sender Adapter - invert reading

Hi all,
Just wondering if there is a way to invert the level reading on the VE. Can resistive tank sender adapter. The level senders I have seem to operate the opposite way round, so when the tank is empty Victron reports it as full and when it's full, Victron reports it as empty (on Colour Control). Is there any way to sort this - if not it would be a nice little feature to add.

Cheers,
