Sensor adheres to the outside of your RV's holding tank to measure its fluid levels, and it sends those readings to a SeeLeveL monitor (sold separately) inside your RV. Can be cut or stacked to fit the height of your tank.

Notes:
Traditional tank monitors have a reputation for being unreliable. With probes mounted inside, they get gunked up and send false readings. When you have only a handful of them, they only measure in quarter increments at best. When you're keeping an eye on how much fresh water you have, the difference between 25% full and empty means a lot, and that inaccuracy can be a problem.
The SeeLeveL tank monitoring system uses technology that can sense fluid levels from the outside of the tank. The sensors' flexible circuit board sticks in place and measures along its entire height. This makes it accurate in single-digit increments.
This sensor has a resolution of 1/4". This means, for example, if the water level in your fresh-water tank drops by 1/4", the monitor will update its reading. If you're used to using probe sensors, just imagine having one of those installed every 1/4" on the side of your tank. That's how accurate it will be using this system.
Easy Install
If you're comfortable with basic wiring, installing the SeeLeveL monitoring system should be a straightforward DIY project.
A single 9" sensor can measure a tank as tall as 10-1/2". For a shorter tank, the sensor can be trimmed. If your tank is taller than 10-1/2", use a taller sensor or stack 2 sensors. This table will tell you which sensor setup is recommended based on tank height:
| Sensor Options | |
|---|---|
| Tank Height | Best Sensor Option |
| 3-1/2" - 10-1/2" | Single 9" |
| 10-1/2" - 14" | Single 12" |
| 14" - 19-1/2" | 2 stacked 9" |
| 19-1/2" - 26" | 2 stacked 12"" |
| Part numbers: Part numbers: 9" (SE78VR), 12" (SE88VR) | |
To get the best resolution for the highest accuracy, choose the right setup. The segments along the left side of the sensor have 4 read points each. The more of those segments you have, the better the accuracy. Even with the lowest resolution possible, you will get tank readings accurate within single digit percentages.
You don't need to be a computer genius to install the sensors either. The sensors are programmed by using scissors to trim the tabs at the top. By altering the circuits, the sensor can tell the display exactly where it is. The included instruction manual will tell you how to trim the tabs during installation. Be very careful when trimming these tabs. The process is not reversible and incorrect installation isn't covered by warranty.
Once you've got your sensors selected and prepped by cutting the tabs, you're ready to install. You're going to want to make sure you thoroughly clean the sides of the tank first. Then, temporarily tape them down. Splice together all signal wires and all ground wires from the sensors, and run those two wires through your RV to the monitor inside. If you're replacing an old tank monitoring system, the existing wiring can be used. Now, run tests to make sure the system works properly. If that all looks good, the sensors are attached to the tanks with the 3M adhesive backing.
Reads up to 7 Tanks
This sensor is the new-and-improved design that is fully compatible with 709 Series tank monitors for measuring as many as 4 tanks. If you've purchased a SeeLeveL monitor for reading your fresh, gray, black, and galley tanks, this sensor will give you the same performance or better, depending on your setup.
This design was also made to read up to 7 tanks with the SeeLeveL Soul system. If your RV has a SeeLeveL Soul tank monitoring system installed from the factory, this is the sensor you need to get if you need a replacement. Older versions of these sensors may not work for you.
Bottom line: No matter what monitor you are using, this sensor will work.

Ratings & Reviews
not needed so I returned it, but not the fault of etrailer.
Got it quickly and came as advertised and is working like it should very happy with it and etrailer was very easy to order it from. Will definitely buy from etrailer again
This was a replacement panel for one of the same model that failed.. the new panel went into place and works well..
eTrailer is my go to for trailer parts. Large inventory and they carry specialized replacement parts. Competiveky priced and fast shipping.
This unit is not "Plug & Play. I am replacing the original (1yr old) SeeLevel II with the 7090-BTP7 and it would not work. Calling Garnet Tech support, the supplied pigtails with plug must be used. Wires from the RV need to be cross referenced.
Excellent service from e trailer unfortunately it is the wrong item to replace the one that is no longer operating.
I installed the system about a week ago. So far it is working beautifully! I have a 2022 Renegade Verona LE and the original Firefly system was never reliable. I installed the panel in my wet bay and use the Bluetooth feature to check the levels when I'm in the rig.
After doing some you-tube research and chatting with the SeeLevel tech team, I felt safe that my unresponsive tank level reading was caused by a faulty tank sensor. This fixed the problem.
I am surprised, and delighted, that eTrailer has expanded their inventory to include RV parts. As always, great selection, helpful videos, fair pricing, and quick shipping all make for a swell experience. Thank you!
I bought this SeeLeveL display to replace one which had stopped lighting up some of the LED segments. I just matched the display functions of the old one when I made my order using the product images on the etrailer website. The new one was a direct drop-in replacement. The connector pins on the new one were bent and had to be straightened which I did by hand with a key. Once plugged in and tested all the displays segments worked based on the tank levels at the time and were brighter than the old display. The display arrived within a few days of placing the order as predicted. I like the etrailer website and the service they provide.
Works great. It's all about placing it properly on the tank to get the proper calibration.
Good service everything got delivered pretty much on time thank you
Have't installed it yet.
Surprised at the extent of the extra charges for customs and taxes.
Yet another great experience with eTrailer. The water tank level sensor was priced right and arrived quickly. I've already installed and it is up and running. I'm a "happy camper".
Was extremely easy to install. Has been great!
The SeeLevel system has worked flawlessly. It is a vast improvement over the tank monitoring system that came with our Airstream.
This was the item I needed. Informative videos, Fair price, fast delivery, fixed the gray tank reading issue. Thank you
