Topargee Surface Mount Tank Gauge

Make managing your freshwater simple and stress-free with the Topargee Surface Mount Tank Gauge — the compact, smart solution for accurate water monitoring in caravans, RVs and boats. Its space-saving design mounts neatly to any surface, giving you clear visibility of exactly how many litres or gallons you have left via the digital display. No more guessing if you’ve got enough water to shower, cook or clean — you get real-time accuracy as you use it.

Installation is quick and fuss-free thanks to the in-line setup (so there’s no drilling into your tank). It’s fully programmable for tank sizes up to 99,999L, with the capacity stored in memory for convenience. Powered solely by AA batteries, it runs without needing a hard-wired connection, making it ideal for tight spaces or off-grid builds.

Even when your rig is parked on uneven ground, the readings stay reliable — finally eliminating those vague “full / half full / empty” guess-estimates. Plus, one unit can monitor multiple freshwater tanks if they share the same pump. Smart, compact and incredibly practical, the Topargee Surface Mount Tank Gauge puts you in total control of your water supply — so you can adventure further with confidence.
