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

I use this to measure water volume on my RV black and grey tanks when I need to clean and rinse them. Works great. Filled a one gallon water bottle to test accuracy, perfect. Forgot procedure on how to switch from liters to gallons (I blame it on old age.). Called the product help phone number. Wasn’t expecting much but was pleasantly surprised to have the call answered on the third ring. The fellow answering was clear and concise with instructions to change back to gallons. Very happy to receive such great service. This is a very good product with very good customer service.

Bought this because we have a limited water supply for lawn irrigation and needed to know exactly how many gallons I use. Durable design, does not leak and the screen is very easy to read and interact with. I have no true way to tell accuracy but it seems constant with my estimates and holding tank levels after use.

Tested and worked fine.My first review was removed "per seller agreement"?The meter was accurate.Parts are brass. Do not use for potable water.

It’s great to know how much water you are putting into a camper so you don’t overfill your black tank on your camper. The battery has lasted over a year now. It seems to be accurate, a great value, easy to read as it counts up. No leakage when you use the o ring gasket.

Great device to have for a travel trailer so that you know how much water you are putting in your tanks. The device is accurate for the most part. I tested it on a 1 gallon bucket and 5 gallon bucket. It was close enough for me to trust the device. Must have when backfilling your storage tanks for cleaning.

Can't speak for accuracy, but functionality is excellent. Seems to repeat quite well. Build quality is good for the price, though I wouldn't recommend attaching any hose without a strain relief.

We have a concrete pond that i have always wondered just how many gallons it holds. So after are clean out and refill this year I used this to get a readingon the gallon amount. Worked perfectly. Thank you

Great product!!! Works as intended and easy to install. Accurate counting and great in small places. I'd recommend this product.!!
