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

Level Indicator for Urine Canisters in composting toilets

Ever had this problem? Your urine canister is full, that last drop of liquid gold makes it overflow – and suddenly, you’re faced with an unpleasant surprise?
Thanks to the level indicator for composting toilets, such mishaps are a thing of the past. As soon as the Urinometer winks at you with its bright orange arrow from the urine funnel, it’s time to act: "Empty it now, or it will overflow!" This clever little helper reliably warns you before any unpleasant accidents occur.

Clean, simple, and secure – the Trelino® Urinometer is the perfect solution if you want to rely 100 % on your level indicator. Ideal for use in composting toilets in vans, motorhomes, garden sheds, boats – in short, anywhere you use your favourite little loo!

How the Level Indicator for Composting Toilets Works

Using a floating mechanism, the Trelino® Urinometer measures the fill level of your canister. As the liquid rises, the float moves upwards, pushing an orange plastic arrow 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 torch or an external display outside the van, as required by alternative products.
Bonus feature: The level indicator is inserted through the membrane of the urine canister lid. This not only ensures a secure fit but also prevents the membrane from shifting – a simple yet effective solution!

Your Benefits

  • No more overflowing urine canisters – ensures clean use of your composting toilet
  • Immediate visual readability – no need for light or external displays
  • Battery-free operation – for maximum independence and reliability
  • Hygienic and easy to clean – using household products like diluted vinegar or natural cleaners with effective microorganisms
  • Simple installation – just insert through the membrane, screw the lid on – done!

Material

  • Polypropylene (PP)
  1. Unscrew the lid of the urine canister.
  2. Remove the membrane from the lid.
  3. Carefully insert the Trelino® Urinometer level indicator through the membrane.
  4. Check that the indicator is correctly positioned. The two small indentations on the round base of the Urinometer should align with the two markings on the membrane. If they match, everything is in place!
  5. Screw the lid with the membrane and Urinometer back onto the canister, place the separating insert into the toilet – and you're all set! :)

Der Gamechanger mit Kindern

Wir sind eine vierköpfige Familie mit zwei Mädchen (5 und 8 Jahre alt). Unsere Mädels kommen super mit der Trenntoilette klar, konnten aber leider am Klag überhaupt nicht einschätzen, wie voll der Urinkanister ist. Gerade wenn wir autark stehen, ist es super unangenehm (und ehrlich gesagt ziemlich eklig), wenn der Kanister überläuft, weil man’s nicht rechtzeitig bemerkt. Ich find ich den Preis des Urinometers schon happig – aber nachdem ich ein paar Mal den ganzen Spaß reinigen durfte, ist es mir die Investition ehrlich gesagt wert.
