If your RV tank monitor readings change from 25% to empty in the blink of an eye, that's a problem. This monitor uses SeeLeveL sensors (sold separately) for single-digit accuracy. Also displays your propane level and battery voltage.

Specs:
Note: SeeLeveL tank monitoring systems are not compatible with metal tanks.
Traditional tank monitors have a reputation for being unreliable. Only a few sensors are installed inside, meaning that they usually only measure in quarter increments and can send false readings if they get dirty. 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.
LPG Monitoring
Large RVs with permanent propane tanks often feature wired sensors on their gauges. These can go by different names, such as LPG gauge sensors, tank level monitors, remote ready dials, or R3D dials. If your RV has an interior panel for monitoring LPG levels, you know you're good to go with wiring already in place for an easy install. If you're not sure, check the tank itself. If the gauge has a wired sensor attached to it, you can connect it to the SeeLeveL monitor.
SeeLeveL sensors used for fresh, gray, and black tanks will not work on metal tanks of any kind, including LPG tanks.

If you are replacing an old tank monitoring system, you'd want to check which functions are being provided by the existing panel. Some models incorporate switches for pumps or heaters or are providing information on propane levels. You'd want to pick the SeeLeveL monitor that can provide for all of these features.

Found a hard to find part for my Airstream trailer at a great price! Plus, very timely free shipping! Can’t beat that!!
I used one of these in another trailer and love it. That’s why I bought one for the trailer I am currently rebuilding. I had a sender problem with one tank and their customer service was wonderful helping me find a solution to the specific problem that existed.
replaced the WGO OEM panel with this one as it had all the options that I needed and fit nicely into the same area... as with the sensors, it was an easy single-wire install (for the sensors) and gives a much more accurate indication of the tank status'... would highly recommend this product!
Combined with the sensors perhaps the best upgrade to my trailer.
Monitor works great. Fast shipping.
Part repaired our tank sensor for our gray tank on our DRV.
I'm looking forward to installing this in the rig to add blue tooth capability to the SeaLevel system. This will make it convenient to be outside of the rig while draining the tanks or adding fresh water.
The SeeLevel system has worked flawlessly. It is a vast improvement over the tank monitoring system that came with our Airstream.
not needed so I returned it, but not the fault of etrailer.
This was the item I needed. Informative videos, Fair price, fast delivery, fixed the gray tank reading issue. Thank you
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
Easy installation and they work great
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.
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!
Great customer service fair price and follow thru…

This was a replacement panel for one of the same model that failed.. the new panel went into place and works well..
Excellent service from e trailer unfortunately it is the wrong item to replace the one that is no longer operating.
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.
Info for this part was:
At etrailer we provide the best information available about the products we sell. We take the quality of our information seriously so that you can get the right part the first time.
