Never Guess Your Tank Levels Again!

"I installed this in under an hour, and the setup was much easier than I expected. The tank readings have been accurate, and I no longer have to guess when it's time to refill or dump my tanks." - Corbin Ashcroft

Why Get Our Wireless RV Tank Monitoring System?

✅ Accurate Tank Sensing: Factory screw-in probes often become dirty, corroded, or stuck, resulting in unreliable tank readings. This Wireless RV Tank Monitoring System uses four external adhesive sensors to accurately monitor liquid levels from outside the tank without drilling, piercing, or contacting waste. Compatible with polyethylene and fiberglass holding tanks up to 12–15 mm thick, it supports fresh, gray, and black water tanks.

✅ Bluetooth & Wi-Fi App Monitoring: Monitor fresh, gray, or black water tank levels in real time from your smartphone or tablet using Bluetooth or local Wi-Fi, with no internet or cloud account required. The free app supports up to 10 TankMaster units, displays real-time tank levels, stores 30 days of usage history, provides predictive charts, and allows customizable alerts before tanks become full or empty.

✅ Quick Installation: Install the system in minutes using external adhesive sensors. Powered by USB 5V or your RV's 12V electrical system, it is built for rugged RV use with low power consumption, over-the-air firmware updates, and Home Assistant compatibility for smart RV monitoring.
