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 battery voltage and features a water pump switch.
Features:
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.

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.

Hello everybody, this is Jeff at etrailer.com. Today, we're gonna take a look at the SeeLeveL RV Holding Tank Monitor for your fresh, gray, and black water tanks, and it comes with the water pump switch. Now, if your RV tank monitor readings will change from 25% to empty in just a blink of an eye, that could be a problem. So with the SeeLeveL Holding Tank Monitor, you could able to display the levels of your RV's fresh, gray, and black tanks with just the push of a button. This does hard-wire to the SeeLeveL sensors that are mounted on the outside of the tanks to give you a single digit accuracy. Those sensors we do sell separately on our website.
This will also display the battery voltage if you push that button, it'll show your battery voltage right there, and with that switch, you can activate your water pump. It's a three-way function switch that'll let you connect to switches in your bathroom, kitchen, or elsewhere. This will check status and signal strength of the sensors using a diagnostic mode, and it'll help improve accuracy during your install. This will also alert you of any errors or calibration issues with the various display codes it'll show, and the codes are basically explained with suggested solutions in the owner's manual. And this does work with multiple monitors, so you can check the tank status from the service bay or inside your RV.
And it does install very easily, all you have to do is cut a hole for the recessed portion to fit into, and then screw it in place with the included hardware. Basically, that recessed portion, if we measure that, it's gonna be right at three inches by 1 3/4 inches by about 3/4 inches, that would be your cutout amount that you would need to have this drop into place. If you noticed, it does include this pigtail needed for installation. Basically, that would just plug in the back there and then wire it to your installation. Now, you can use the existing wiring from your old tank monitor system to help ease the installation.
Application again for this is three holding tank systems, a fresh, a gray, and black water. Operating temperature range, 32 degrees Fahrenheit to 140 degrees Fahrenheit, and the voltage range is 11 volts to 16 volts. Last thing I'm gonna do is just give you the measurement of the monitor itself, It's gonna be four inches wide by 2 13/16 inches tall, and your total depth from the whole thing is gonna be right about 3/4 of an inch. But that should do it for the review on the SeeLeveL RV Holding Tank Monitor for the fresh, gray, and black water tanks with the water pump switch..

Ratings & Reviews
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
This was a replacement panel for one of the same model that failed.. the new panel went into place and works well..
Easy installation and they work great
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.
Very good
Great price, fast shipping
Installation was easy and so happy my monitor could be replaced. Very satisfied with your company.
New part works perfectly.
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.
eTrailer is my go to for trailer parts. Large inventory and they carry specialized replacement parts. Competiveky priced and fast shipping.
