P3 P0550 Water Meter

Worked great on my cattle tank. made it easy to see what the use was and if I had leaks.

Purchased prior to taking a RV trip to Alaska for 4 months. I wanted to have accurate readings while filling my freshwater tank because I found the dummy lights in most RV's are not accurate at all. It worked perfectly for a while but then it actually came apart on the female connection end. Well, it's out of warranty but I'm now home and called the manufacturer through Amazon to see if they would still replace it for me. Without hesitation they said "No Problem" they would send me a new one. They indicated that I probably overtighten it on the hose which likely caused it to come apart. In any case, what GREAT service and understanding. This is a great little product and would highly recommend for all RV'ers on the road............

These hose meters do work well although I did mark it a star down just because if you do not use a in line filter they plug up very easily and stop working. If you use an inline filter then they work perfectly. They should actually sell an inline filter as an add on and recommend the purchase with the meter. I used it in two different situations on our farm. The first was for an inline drip irrigation system that needed to meter the amount of water to the system and the second was hand watering with a wand in a situation where each plant needed precisely 5 gallons each and on certain days and 10 gallons each on other days. I can imagine that if you are paying for city water it would be very beneficial for everything such as filling pools, watering plants, washing the car (so you can see if it would be more cost effective to go to a car wash). One test that we performed to calibrate frequently was the filling of a 5 gallon bucket. Anyway, this is a good purchase and very useful garden gadget. I would definitely recommend!

useful dual reading gauge - for intermittent and total flow. helps in filling trailer fresh water tank. Although plastic, seems to survive my rough treatment.

We ordered this water meter May 30, 2025 to use with our RV external tank flush system. It worked great. Now it’s worthless. We began a 26 day; 9 stop RV trip on April 10, 2026 after using the water meter intermittently for 10 months. It’s dead. It will not register a single ounce of water anymore. It’s not that the batteries are dead: the display comes on just fine. It just continuously registers zero gallons. It’s just exactly as helpful as not having a meter in place at all. Worthless.

Great meter

Perfect for camper and gaging how many gallons is going in

Be sure to get a bucket with a known size. I used a two gallon bucket and the meter measured 1.6 gallons. The product is useful just not accurate.

Didn't arrived at all, don't know why they ask me to write a review on this. India with love

Using to measure gallons pumped out of rain water well in back yard,wore our after a couple of years (DUE TO DIRTY WATER I SUPPOSE) +or - 55,000 gallons

Buen producto, para ser un producto pequeño, si cumple la función de medir los litros de agua utilizados, lo recomiendo para usos caseros.

Easy to use and serves a purpose only it can-how much is going through the line! Came on time and of great value

Tengo fermentadores de 59 litros y, dependiendo la receta, a veces me sobra producto que meto a otro fermentador pero nunca se llena. Utilicé este medidor de fluidos y es excelente, ahora se que mi sobrante, dependiendo la receta, va de 12 a 29 litros.
