RESTMO Water 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

If you need to know how much flow, then slow your role. This be the meter. You’ll be swatting skeeters while watching this meter. Seriously though, good stuff. No leakage, easy to read, use and install. This is a good brand. This is aReturning customers opinion. Please use one of these if you are backfilling your black tank.

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

hard to see the decimal point. In fact it is almost invisible. When I filled RV I saw 25 on it and it looked like 25 gallons. No way I put in 25 gallons that fast! So after a bit of looking I saw that the last digit is "after" the point that you can barely see. Other than that it works pretty well.

Works fine for me - pretty accurate too. Helps me to ensure we fill our RV tanks correctly.

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.

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.

When I fill my RV with water, I use the onboard monitor to tell me when it's full. I do this because when I fill it until the water comes out of the overflow tube, I got leakage inside the RV. The onboard monitor will register full when it's about 3/4's full, so I have to retrieve and filter water more often when we're out for a week or more. This will allow me to get a full 35 gallons without an overflow and keep me informed of my water usage when irrigating my lawn.Update: I found out I don't have a 35 gallon tank, I have a 25 gallon tank with a 6 gallon water heater (contrary to the manual), and I use 410 gallons of water to irrigate my 1/4 acre lot.

Died after 3 uses in under a year. Thought it was the battery since the display only showed partial characters, but nope. Changed using multiple batteries (all had above 3 volts), but display never came on again.Update: After I initially gave a 1 star review the seller contacted me. Even though the purchase of the water flow meter was a year ago, they still refunded my purchase since it stopped working. They also offered to send me a new one for free.Never expected that. Great company to purchase from.
