RESTMO Water Flow Meter with Brass Inlet & Outlet, Measure Gallon/Liter Consumption and Flow Rate for Outdoor Garden Hose Watering, RV Water Tank Filling, Lawn Sprinkler and Nozzle Sprayer

I used this to measure and mark levels on a storage tank. I had reservations at first since the device seemed so simple with just a plastic impeller that spins in the water flow. I tested it first on some known measures to make sure it was reading correctly and it was spot on accurate with what I expected to see.The clear LCD screen was easy to read and simple controls made it perfect for what I needed. Since it is made of a durable plastic case with metal fittings and a replaceable battery, I expect this is the last one I will ever need to buy.

Why did you pick this product vs others?:I bought 2 of these. After about a month 1 stopped working, changed the battery still nothing. Called them up and they shipped me a new one immediately, great customer service!

My husband loves this to measure the water he puts in his sprayer tank. It is so much better than guessing how much you have in the tank.

Easy to use, very effective and love that it has metric measurments as well. I will be buying another one for a second filtration system I have to know when to replace my filters. This is a HUGE life saver when you own an RV! Knowing what goes into the tanks and flows out, helps you keep better track of how the RV tanks are filling before the need to dump them. Great item. Highly recommend!

Seems to work quite well

Works great plastic one broke second time I used it this one is sturdy

Why did you pick this product vs others?:Recommended by a friend.

It counts the water volume. I used a 2 L measuring cup to check it and it was correct. I am using it with hydroponics to measure water quantity when creating large quantities of nutrient solution (200L or 1000 L). So far, so good.
