"Urinometer" Level Indicator Mechanical Overflow Protection for Trelino® Evo Composting Toilets
Say goodbye to guessing when it’s time to empty your toilet. The Trelino® Urinometer level indicator gives you a clear, instant way to check urine levels before they become a problem. No more unexpected overflows or messy clean-ups.
Designed to work seamlessly with Trelino® Evo composting toilets, it uses a simple floating mechanism to track the fill level inside the canister. As the liquid rises, a visible indicator appears, letting you know exactly when it is time to empty.
With no batteries or wiring required, it is a reliable, low-maintenance upgrade for any off grid setup. It keeps things simple, practical, and easy to manage, whether you are travelling solo or with family.

Avoid Messy Overflows Before They Happen
The built-in float system rises with the liquid level and signals when the canister is nearing capacity. This helps prevent overflows inside your setup, reducing clean-up and keeping things hygienic.

A quick lift of the lid reveals a clear visual indicator, so you always know where things stand. There is no need to open containers or rely on external monitors.

No wiring, no charging, and no electronics to fail. The mechanical design works reliably in all conditions, making it ideal for off grid travel and longer trips.
Simple to Use for the Whole Family
The clear visual indicator makes it easy to see when the canister is getting full. It is simple enough for kids to understand, helping everyone use the toilet correctly without guesswork or constant checking.
