Using the Mopeka Water Tank Sensor for my Black Tank.

- Mopeka's new Water Tank sensor is suitable for use with fresh water and gray holding tanks, but not black tanks. Anyway, I ignore that and install one on my black tank anyway. You will have to watch the video to see how it works.

So sorry your Dad is gone, he did a great job and even now is still helping fellow rvers long after he crossed over. I'll bet he's up there now, in the perfect rv that never needs repairs, just waiting to show us all that it is possible to make one that never breaks! Condolences.
Brilliant idea with the deck plate for access. I have wireless thermometers installed in my underbelly and have been struggling with an easy access. This will work great for both!
Glad you liked the idea.
@@RVProject yep I ordered two deck plates and the tank sensor for my fresh water. I've had the propane sensors and love them, I knew they were working on these but I had forgotten. I also subscribed!
Very interesting. But I really am glad I installed the SeaLevel II system. It works and you don’t have to replace batteries
I have the SeeLevel system as well, but when I ran across this product, I thought it might be an easy alternative for those that did not want to wire up such a system. Thanks for your input.
Thanks for sharing. Any updates? How has it been working a year later? Accuracy? False readings?
Did you ever test this out to full tank? I'd love to know.
thanks for sharing. you crushed it with the solution to replaced the battery. A+ there.
wondering how it works in fresh water. for boondocking / off grit is the most important measurement. and the original RV only have 3 levels.
im subscribing and looking forward for updates on this test. thanks
Thank you for your support.
I found the boat deck plates interesting, but for another possible use. Our 5th wheel has a squeaky floor in one spot in the bedroom that drives me nuts! The location of it is up in the 5th wheel nose, between the pin box area and the front storage toward the pass side of the RV. No access from anywhere I can get into to locate squeak and apply lube (or shim to eliminate movement). You see any reason that I couldn't install a deck plate under the nose in the general squeak area?
I don't want to be an alarmist, but an all too common issue in a 5th wheel is the frame area under the nose is often a weak spot, and/or may have a bad or broken weld. I would be concerned with a squeak in that spot.
A deck plate might help, but it is going to show for sure, so I would see that as a last resort. What the factory normally does when repairing such areas is to remove the rubber strip along the aluminum trim. There are screws under that strip.
To disassemble that area, you would have to remove the screws and caulking underneath and slightly bend the aluminum trim strip out so you can see behind it.
But if you do that, unless you are experienced at doing so, there is little chance you will be able to get the trim strip reattached without severely bending it.
My advice is that if you have any suspicions of a bad weld on the frame to take the 5th wheel to a good RV shop. Best of luck.
Any updates on the black tank?
you know we've been living in our 5th wheel for coming up on 5 years and this is the 1st time I've ever seen anyone explain the quick access door through the underbelly. Either I'm not watching the right videos or I don't pay attention... lol Great tip, man. I'm going to get under the RV and change my crudely cut and duct taped access holes in the near future for sure. If you haven't figured out, I'm not the most innovative guy... lol How easy is the battery to change in this sensor? I had the LP sensors in the past and when the batteries died I tried to replace them but ended up ruining one of the reading sensors when I took the assembly apart.
The deck plates are standard boat items. When I had boats (prior to RVs), there were several deck plates for access into areas of the boat.
The battery is accessed by popping off the cover with a screwdriver.
Any updates on this product usage?
I foresee a need for calibration of both full and empty. What's the point of precision based on faulty assumptions? Bluetooth access for filling the fresh tank might be nice.
The OEM sensors are fairly crude, and have low resolution - that is, if they are working - which is not often for at least the blank tank.
The OEM tank gauge indicates empty, 1/3rd full, 2/3 full, and full. Not a very good resolution. Thus, at best, the OEM sensors are only 32% accurate.
For example, if the tank was actually 65% full, it would still only read 1/3rd full, or only 32% accurate.
So if the Mopeka sensor is say 10-20% accurate, and always works, then it would still be an improvement in both areas, no?
So even if the Mopeka sensor is not 100% accurate, it is still likely to be more accurate than the OEM sensor, and more reliable.
However as I stated in the video, I have only tested the device for one trip, so I do want to try it out awhile longer before I can provide a recommendation.
It does seem odd that when it's made for gray water tanks it doesnt show levels heading to full. I've had my shower and sink back up because gray water monitor said only 2/3 full. Now I know 2/3 is full on mine. Also, where and what kind of battery does this use? I see you have Mopeka incorporated onto your monitor panel. How is that done?
It uses a coin cell CR3023 I think. For the mounting of the Mopeka display, I had a panel custom built which allowed the display to be back mounted.
I have a whole series of videos that are indexed on my website ( www.rv-project.com/projects/rvtankcheck.php) that includes a smaller (and less costly) panel for the Mopeka display.
What is the result after the year?
Can we use for the fuel tank
Curious if your having issues with your see level II monitor on the black tank?
No issues. But I do use the RV as a test bed so I can do these videos.
I still prefer the SeeLevel though as I have a display unit in both the main console of the RV as well as a second monitor in the wet-bay area.
I like that I can fill the fresh water tank or dumping the holding tank and monitor the tank levels in the wet-bay.
If I had to use a cell phone to monitor the tanks will filling or dumping, it would be a bit more inconvenient I think.
Thanks for sharing Like #35 view #197. You would think they would have high level notification for the gray tank.
It would be easy for them to fix. It would only require a change to the software. It's been my experience that Mopeka is pretty good at improving their products, so perhaps that will be a future improvement.
That would be great if they could get that working better I would buy those in a heartbeat 💗
I am going to test it more next year. It is possible that the ultrasonic approach may never be quite 100% accurate as the solids content is variable.
I did reach out to Mopeka and so far, they have not responded.
Given that, if the transducer is even 75% accurate, it is a lot better than what most of us have now.
I will publish an update video next year as appropriate.
@@RVProject right on I appreciate that I would like to see a follow up your probably right anything is better than the stock reader I did like the idea of putting in the port hole opening to make it accessible as like your trailer mine also has a heated underbelly with the corplass thanks 😊
Any reason this couldn’t be mounted on the side of the tank? It would be much easier to change the batteries on my boat.
This type of sensor is measuring the level of fluid based on tending sound waves through the tank and fluid inside. It cannot to that horizontally across your tank.
I commend your reverse engineering of a products🤝
Thanks for watching.
Do you know where I can buy this sensor in Germany?
Unfortunately I do not.
Don't you guys hate when the poster doesn't reply? probably had a stroke.
