RESTMO Water Flow Meter DE-O-WM-2P-GY with Brass Inlet and Outlet

RESTMO Water Flow Meter DE-O-WM-2P-GY is a hose-mounted meter with brass inlet and outlet threads and four display modes. It tracks live flow, last-use consumption, a weekly daily average and total water use, with gallon and litre units. Customer feedback reports straightforward operation but mixed experiences with accuracy, construction and leaks, so it is better suited to monitoring than to applications requiring assured precision.

At a glance

Four button-selected modes show real-time flow, the previous watering session, weekly daily average or total use.
The meter can switch between gallon and litre readings.
An LCD automatically sleeps after one minute with no button operation or water flow.
The listing describes brass inlet and outlet threads and claims an IPX6 waterproof grade.

Customer feedback is mixed on accuracy, with some reporting significant inaccuracy despite the listing's stated tolerance.
Reports of leakage vary, and some customers also describe the build as less sturdy than expected.

What to know before buying

Listing details to confirm

The manufacturer claims measurement tolerance of less than 5% and an IPX6 rating, but these are listing claims rather than independently verified performance. The button changes units in Flow mode and resets data in the other modes. Keep hands dry when opening the battery tray, install the battery in the correct direction and lock the compartment.

Who is it for?

A good fit for

Gardeners who want to monitor hose flow and track water use across watering sessions.
RV or trailer owners who want a displayed usage reading while filling or back-flushing a tank.
Buyers who prefer a simple button-controlled meter with gallon or litre readings.

Less suited to

Users who need independently verified measurement accuracy or leak-free performance for critical water accounting.
Anyone seeking a connected or app-based meter, which is not listed as a feature here.

Customer feedback is broadly favourable about functionality and ease of use, with a specific mention of back-flushing trailer holding tanks. Experiences with accuracy, build quality and leakage are mixed, including reports of significant inaccuracy and leaks. For routine garden or tank monitoring, the four modes and unit switch offer useful context, but buyers who depend on precise totals or dry connections should account for that variability. Aggregate ratings lean positive overall, but do not establish why customers rated the meter as they did.

Positive themes

Customers describe the meter as functional and easy to use.

Mixed feedback

Accuracy feedback ranges from very accurate to significantly inaccurate.
Build quality is described positively by some and as not especially sturdy by others.
Leakage experiences vary, with some reporting no leaks and others reporting significant leakage.

Frequently asked questions

What does the RESTMO meter measure?

Its four modes show real-time flow, the last-use amount, a daily average over a week and total water use.

Can it display litres as well as gallons?

Yes. The listing says to long-press the button in Flow mode to switch between gallon and litre units.

Does the listing guarantee accuracy below 5%?

It claims measurement tolerance of less than 5%, but customer feedback on accuracy is mixed, so treat that figure as a manufacturer claim rather than verified performance.

What should I know about resetting readings?

The listing says a long press in modes other than Flow resets data. Check the display mode before holding the button.
