"Urinometer" Level Indicator for Composting Toilet Trelino Evo

Know at a glance when it’s time to empty the urine canister – with the Trelino® Urinometer, the mechanical overflow protection for your Evo composting toilet!

Using a floating mechanism, the Trelino® Urinometer measures the fill level of your canister. As the liquid rises, the float moves upwards, pushing the signal pin through the urine funnel of the separating insert. Once the canister reaches a critical level, the orange arrow becomes clearly visible.

The Urinometer level indicator requires no batteries, making it highly reliable and ensuring maximum independence. A quick lift of the toilet lid is enough to check if it’s time to empty the canister – no need for a light or an external display outside the van, as required by alternative products.
