Know exactly how much fresh water you have left, without relying on float-style guesswork. This Bluetooth Water Tank Gauge uses your phone as the display and shows the remaining water in liters or gallons, giving van owners and other mobile users a simpler way to monitor water usage with more confidence. Designed by Topargee in Australia, this gauge is built for freshwater tank monitoring in vans, RVs, trailers, boats, and off-grid setups. It works with pressurized and gravity-fed systems, installs inline on the water line, and does not require anything to be drilled into the tank. If you prefer to use a mounted LCD screen instead of your phone, see the Flush Mount Water Tank Gauge page.
This gauge tracks water use from the programmed starting amount. After refilling the tank, the gauge must be reset so the stored total matches the amount of water in the tank.
The sender installs inline on the water line and the gauge tracks water use from the programmed tank amount. Your phone displays the remaining water in liters or gallons through the Bluetooth app.
No. The gauge uses Bluetooth, so you can check water levels without an internet connection when you are within communication range.
Yes. After you refill the tank, reset the gauge so the stored total returns to the amount currently in the tank.
Yes, but you need to update the gauge total to match the amount of water currently in the tank so the count remains accurate.
Yes. The app remembers the device, and the gauge stores the settings and totals in the Bluetooth module.
Yes. It can run on 2 AA batteries or with the optional Topargee 12V adapter.
No. Do not wire 12V directly to the gauge. Use the correct 12V adapter.
For best results, install the sender about 200 mm after the pump and away from 90 degree elbows. If space is limited, it can be fitted before the pump.
No. The sender and extension leads should not be cut or joined. Use the proper extension lead if you need more length.
The sender has 1/2 in BSP male threads. Many customers use 1/2 in BSP female to 1/2 in NPT male adapters, or other compatible plumbing fittings that suit their hose and system.

So far so good. Installed on my Sportsmobile converted dodge promaster. Waiting for the rain to see how it does in wet conditions. Once I figured out how to install it was VERY easy. Only ask would be more details on initial installation process since I wasn't sure exactly where to place the track. Once I got it installed and put the fly in the track it was so easy. Excited for how this will work on my pop-top van.
Love it! I researched a lot before deciding on Orion. I just think their design out looks all the others. This is functional, solid, and easy install. Customer service was excellent. They answered all my questions. I didn’t build my van, I bought it already done. Solar panel and all, I was able to move the solar panel to a better location using their solar panel brackets, I’ll easily add some decking following their recommendations of what decking product to use, and be able to store items I don’t want in the van. Love supporting a local Oregon business. Would recommend them to everyone. Oh and I got the rack with the lights. Totally recommend. The install was perfect and they really light up the night!
Thank you, Krysta! It’s so great to see everything come together on your van. We’re glad we could help you get the solar placement dialed in and plan for decking and extra storage. And thank you for sharing the videos showing off the rear scene lights and flush solar brackets; they’re a huge help to others planning their setups! We really appreciate your recommendation and support for a local Oregon business. Enjoy your adventures!
The ladder is awesome. Super solid. Customer service was also super awesome. Answered my zillion questions quickly through email. Orion products just look so sleek and … stealthy. Glad to support a local business as well. Maybe that’s why shipping was next day.
Hi Krysta, thank you for the video! Glad you love it! Made in Oregon!
great customer service and communication
Love the Stealth+ rack for my 2026 Ford Transit. Orion's team has been great to work with. Everything arrived on time and is high quality. Installation instructions via the PDF on their website were excellent. Text and graphics in the instructions were accurate and contained just the right amount of information.
