Mopeka pro universal

[mikejay]

Anyone else fitted one of these to there water tank? I got one from lpg shop in December but only fitted it about 3weeks ago. From the off I could not get any of the quality stars to light up on an empty tank so could not proceed with the app install. But noticed once I had about 12litres in my tank the quality stars all lit up and it showed a percentage of water. But this is then totally inaccurate and a full to the brim tank shows 88%. Mopeka have been great with there help and I logged water percentage as I added 6litres at a time up to full 96litres. And

Why? Is it a cliffhanger I asked if anyone else had fitted one to a water tank to see what there experience was. Lol dunno what happened there on my phone and it would not post at 1st

I have them on waste fresh and underung gas tank. One calibrated I find them pretty accurate as long as the camper is fairly level. It is essential to position them as directed with the grease on the centre contact to ensure a good connection. You could try deleting the sensor from the app and resetting it should you find it inaccurate. You do need to play around with the tank measurements and volumes. I recommend you do this with the tank full so you know the perimeters you set will be accurate.

Iandsm, when you fitted yours did the quality stars light up on an empty tank. Mines on the bottom of my fresh watertank thats made from black plastic. And I have tried it with different amounts of grease and even without. And no matter what I can only get the quality stars to light with about 12litres in the tank. Mopeka got me to upgrade the firmware on it and it made no difference at all.

Thanks for your reply Mike

My Mopeka Pro Sensors work fine.
I have one on a Gaslow bottle, magnetically attached on the underneath.
I have one on the Fresh Tank - also made of black plastic like yours.
Now my fresh water sensor is wedged into place very firmly so it is pressing on the underneath.
I don't really know what the grease you are talking about is for? maybe to avoid any airgap between sensor and tank? Don't recall any grease but I did fit mine back in 2024 so maybe used and forgot?
And I don't know what "quality stars"? something to do with signal strength of sensors?
Calibration is a key factor though and I think need to accept that the readings will also likely fluctate a bit on the typical fresh water tank which tends to be quite shallow so when on an incline the volume change will be exaggerated.
My Fresh Water has been empty for 3 months now so can't check any readings, but as I fill it up for some travel, I'll be comparing what the Mopeka tells me with what my water meter is telling me. (The Mopeka is good to see how much water you have left, but the water meter is great to see how much water you are putting in. Use the two together to avoid the typical overfill )

Thanks for your reply wildebus,
The quality stars are the fit of the sensor with no water I get no stars so the sensor won't register anything. And when installing the app you can't get past this stage when it checks quality it asks you to adjust the sensor or add more grease they call it sonic grease comes with the sensor think its just silicone grease. Few pics of what I mean its sounding like mopeka are correct and it's faulty so still trying to get lpgshop to answer me. The pic with 1 star is with 12litres of water in the tank no stars is anything from empty upto 12litres. Sensor is in its plastic clip that you glue to the tank which was spotless.

Ah, ok.
I never used the App apart from an initial having a go with it. I connect mine to the Victron system, so maybe that bypasses this check? The biggest issue I has was probably mounting the fresh tank sensor. Had to go underneath the van to remove a service panel (the Autotrails have their big service cap on the bottom of the tank rather than the top accessed from above) and then just 'pressure fit' the sensor as the tank woul accept no kind of adhesive whatsoever.

Yeah I bought it to integrate with my venus os raspberry pi control panel I made but is useless at the moment. I had to drop my tank and take the plywood bottom off and cut a circular hole so I could stick the sensor to the bottom. I can alter the tank settings in venus so when its full it reads full. But as it says my tanks empty at 12 litres its not accurate. Any yes you are correct you don't need the app if using it with victron although mine had a firmware update that you need the app for.
