Restmo O-WM-4P 2-Pack Water Flow Meter with LCD and 4 Modes

Tips for day-to-day use

Each Restmo meter measures 3.8 x 2.2 x 2.2 inches and uses a heavy-duty ABS plastic body. This two-pack gives you a meter for more than one hose setup, such as a garden watering station and an RV tank-filling hose. The LCD and one-touch button make it straightforward to check water use while the hose is running.

Choose FLOW for the real-time rate, CONSUMPTION for the last use, AVERAGE for the daily average over a week, or TOTAL for cumulative use. Need to track a watering session rather than estimate it by time? The different readings help you match the view to the task.

Benefits

The four display modes support different outdoor tasks without requiring you to rely on a single reading. FLOW shows current water rate, while CONSUMPTION and TOTAL help you keep an eye on usage for a specific session or over time. AVERAGE shows daily average use for a week, counted from the next day. Long-press the button in FLOW mode to switch between US gallons and liters, in the other modes, a long press resets the data.

The 360-degree rotating inlet and 3/4-inch hose thread are designed for connection to garden hoses or hose nozzles. A Hall-type sensor and IC chipset perform the measurement, with a stated tolerance under 5%. For accurate counting, use a garden hose at the outlet and maintain a flow of at least 0.6 GPM (2.5 LPM). The display automatically goes to sleep after one minute without operation or water flow.

Compared with estimating water use from run time, a meter gives you consumption and flow readings to reference while watering, filling an RV tank, or setting up a sprinkler. Customer feedback often highlights ease of use and usefulness for sprinkler, RV, and pool-water tracking. Comments on durability and display readability are mixed, so those experiences vary.

Questions before you buy

What do the four modes show? FLOW displays the real-time rate, CONSUMPTION shows the last water use, AVERAGE displays the daily average for a week, and TOTAL tracks total water use.

Can I change the measurement unit? Yes. In FLOW mode, long-press the button to switch between US gallons and liters. Long-pressing in another mode resets that mode’s data.

How does it connect to a hose? The meter has a 3/4-inch hose thread and a 360-degree rotating inlet for connecting to garden hoses or hose nozzles. For counting, the outlet should have a garden hose attached and water should flow at 0.6 GPM (2.5 LPM) or more.

Final verdict

The Restmo O-WM-4P two-pack suits outdoor watering and water-filling tasks where seeing both flow and usage is useful. Its four readings, gallon-or-liter selection, and hose-thread connection make it a practical fit for keeping track of garden hose use, sprinkler watering, and RV tank filling.
