## Description

## 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.
