FAQ Urinometer

  1. How does the level indicator work?
    Our level indicator operates mechanically, without electricity or batteries, making it perfect for independent use on the go. Inside the urine canister, there is a float that pushes a small signal pin upwards as the fill level increases. When this pin is visible upon opening the toilet lid in the separation unit, it’s a clear sign: It’s time to empty the canister.


  2. Which Trelino® models is the level indicator compatible with?
     Our Urinometer has been specifically developed for the Evo series. If you have a different toilet and would like to use a Urinometer, feel free to send a short message to our customer support at hello@trelino.com.


  3. In which sizes is the level indicator available?
    The Urinometer is available in two sizes. The short version fits the Trelino® Evo S, while the long version is compatible with the Evo models M and L. When ordering, simply select the size of your Evo model, and we will send you the appropriate version of the Urinometer.


  4. Can I retrofit the level indicator if I already have a Trelino® Evo?
    Yes, you can use the Urinometer with your existing Evo. The level indicator is easily inserted into the lid of the urine canister. The installation is very straightforward and takes only a minute. No complicated fiddling, no drilling or sawing into the body. On our website, you’ll find an informative video that shows you how to install it in detail.


  5. Does the level indicator require electricity or batteries?
    No, the indicator works 100% mechanically, without any power source – making it completely independent. You’re fully free from batteries or chargers, making it perfect for your next off-grid adventure.


  6. How do I install the level indicator?
    The installation is very simple: First, push the level indicator through the membrane and then insert both the membrane and the Urinometer into the lid of the urine canister. Done! A detailed guide is included in the packaging or can be found on our website.


  7. Is the level indicator also compatible with other urine canisters?
    Yes, our Urinometer is not limited to Trelino® urine canisters. It can also be used with other compatible canisters. If you own a separation toilet from another manufacturer, feel free to send us an email. Our customer support will get in touch with you and let you know if the Urinometer is suitable for your toilet: hello@trelino.com.


  8. How do I clean the level indicator?
    We recommend using our premium cleaner, Holy Shine, or another pH-neutral cleaner for cleaning the Urinometer. You can also use diluted vinegar just like with your separation toilet. With the Urinometer, please avoid using aggressive cleaning agents!


  9. What is included in the delivery of the Trelino® Urinometer?
    You will receive a pre-assembled Urinometer consisting of a holder and a signal pin. Additionally, a silicone membrane for the urine canister is included. The entire set is packaged in a stylish box made from recycled paper.


  10. Does the Urinometer affect the flow rate into the urine tank?
    The Urinometer has been specially designed for use in the urine canister. A smooth flow into your urine canister is still guaranteed. The ring-shaped design of the Urinometer fits perfectly into the lid of the canister and the shape of the holder is specifically tailored to our silicone membrane, so you don’t have to compromise on functionality.


  11. Can I use the level indicator during my period?
    No worries – you can use the level indicator during your period. The indicator measures the fill level of your canister regardless of whether menstrual fluid is present in the urine. It works reliably even during your period.


  12. How often should I clean the level indicator?
    We recommend cleaning the Urinometer, just like the urine canister, regularly every 2-3 days. About once every two weeks (or before you store your Trelino® for a break), a more thorough cleaning with diluted vinegar or citric acid is recommended. This way, everything stays hygienic, fresh, and always ready for use!


  13. Can I use the level indicator without a membrane or with a different membrane than the one from Trelino®?
    No, the Urinometer has been designed to work optimally with the Trelino® membrane. Using it without a membrane or with another type of membrane may impair its functionality.


  14. What should I do if there is a smell?
    Odours can be eliminated with a stronger vinegar or citric acid solution. Let the level indicator soak in the solution for a while. If you’re unsure or need tips: Our support team is happy to assist you! hello@trelino.com
