Diivoo Water Flow Meter with 180° Removable Panel, 4 Measure Modes, ±5% High Accuracy and IP54, Measure Gallon/Liter Consumption and Flow Rate for Outdoor Garden Hose Watering, RV Water Tank Filling

Works well, can be calibrated if necessary, good price, recommended

I recently purchased the Diivoo Water Flow Meter, and I’m extremely impressed! The 180° removable panel makes it super easy to read and operate, even in tricky outdoor spots. With four measurement modes, I can track both gallon and liter consumption as well as flow rate, which is perfect for my garden hose and RV water tank filling needs. The accuracy is impressive—within ±5%—giving me reliable readings every time. Plus, the IP54 rating means it holds up well against outdoor conditions, which is a huge plus. It’s simple to install and has already helped me monitor and manage water usage more efficiently. Overall, a fantastic tool for anyone serious about precise water management outdoors! Highly recommend.

We needed to know how much water we were putting in our trailer's tank. This does the job. Take it along with us for refilling. Don't want to carry to much water. That's just extra weight. Easy to read, easy to use.

Works as expected.

I purchased to measure water flow rates. This one is only rated up to around 11 GPM. My line is higher than this so I couldn't get an accurate measurement. Other than that, it worked pretty well if you are only wanting how many gallons have been used.

Great price and appears to be good quality - time will tell. What really makes this stand out from similar flow meters is the display can be orientated to be read from any direction and It can also be calibrated for accuracy. I also appreciate that it wakes up in the selected gal or liter mode. I use it to fill our camper so I can partially fill the tank and not carry more water than needed. I think it will come in handy for black tank flush too. Update: I’ve used it over two years now and I am impressed with the design, quality, battery life and usefulness.

I tested the flow meter with a 5-gallon water bucket and found that the ±5% accuracy is spot on. I made a minor adjustment to the flow metering (easy to do) and got the flow very close to the five gallons it measured. The meter comes with everything you need for proper operation and connection. I did not have any water leakage between the meter and water hose, even without using the included PTFE tape. I like that you can rotate (flip) the view of the meter's screen, which makes it easy to read while using. I plan to use the Diivo meter to confirm the amount of water in my travel trailer's freshwater tank.

This thing worked great! Came with a battery and that was a real help with a last minute need. We used in conjunction with our RV black tank flush to see how much water was going back into the tank so we wouldn't have an issue. Did not leak at all and the fittings were good quality in my opinion

Supe de este medidor por un canal reconocido de youtube que hace pruebas con hidrolavadoras y es el que usa para dar sus números. Probablemente haya un ligera variación en sus datos, en la descripción incluso habla de un 5% +/- pero creo que funciona muy bien y como se espera. Lo recomiendo por ejemplo para medir el comportamiento de tu hidrolavadora. En mi caso probé con la Ryobi automotriz y próximamente la compararé con la McKillans HF1. Seguramente el método de la cubeta sea más preciso pero no necesito tanta precisión para medir los galones, así que con este equipo es más que suficiente y sobra. Dejo un pequeño video de demostración (una disculpa por el audio pero hasta el final me di cuenta que grabó con el micrófono del cel no el externo 🥴.

Es muy bueno y funciona perfecto
