Product guide

Restmo O-WM-2P Water Flow Meter, Four Modes

Restmo O-WM-2P is a hose-mounted water flow meter with an LCD and four readout modes for monitoring flow and water use. Its listed range, brass-thread connections and unit switching suit garden watering or hose-based filling, while the claimed measurement tolerance and mixed customer feedback on leakage are worth considering.

At a glance

Four modes display real-time flow, last-use consumption, a weekly daily average counted from the next day, and total use.
The listing specifies brass 3/4-inch NH female inlet and male outlet threads.
Long-press controls switch units in flow mode or reset data in other modes. The screen sleeps after one minute without operation or water flow.

Pros and cons

Pros

Separate flow and consumption views can help track both current watering and accumulated use.
The listing includes a CR2032 battery, so a battery is specified as part of the package.
Gallon and litre readouts provide a choice of units.

Cons

The stated measurement tolerance is ± 5%, so readings are not presented as exact.
Weekly average tracking starts counting from the next day, rather than providing an immediate same-day weekly average.

What to know before buying

Listing details to confirm

The listing states ± 5% measurement tolerance and IPX6 protection. Customer feedback describes ease of use, water-use readings and sturdy construction positively, but reports mixed experiences with leakage. Confirm hose-thread fit and check connections for leaks during setup. The listing also describes brass inlet and outlet threads while naming ABS as the meter material, which appears to distinguish the threads from the body.

Who is it for?

A good fit for

Gardeners who want to monitor hose flow and accumulated watering use.
Buyers filling tanks or using a hose who can connect to the listed 3/4” NH threads.
People who want both gallon and litre readouts and several usage views.

Less suited to

Anyone who needs a measurement tolerance tighter than the listed ± 5%.
Buyers whose hose connection does not match the listed 3/4” NH threads.

Customer feedback describes the meter as easy to set up and use, with useful water-use readings and a sturdy feel. Experiences with leakage are mixed, so buyers should pay attention to connection fit and inspect the joints after installation. These reported impressions are separate from the listing's stated ± 5% measurement tolerance and IPX6 protection. The aggregate ratings lean positive, but ratings alone do not establish performance or explain individual experiences.
