RESTMO O-WM-2P Water Flow Meter 2-Pack, Brass Threads, 4 Modes

For gardeners and RV owners who want to track hose water use as well as flow, the RESTMO O-WM-2P two-pack provides four measurement views on an easy-to-read LCD. Use a meter at an outdoor faucet or hose connection to monitor watering, sprinkler use, or RV tank filling.

Switch between gallons and liters, then check current flow or recorded consumption. The brass inlet and outlet threads are designed for repeated hose connections, making the meters useful across more than one watering or filling setup.

Tips for day-to-day use

Attach the female inlet to a compatible 3/4” NH hose or faucet connection, then connect the hose to the male outlet. The brass threads suit setups that are connected and disconnected regularly, such as moving a meter between a garden hose and a sprinkler line. During watering, the real-time mode shows flow in GPM or L/min, the consumption modes help track a single use, a weekly daily average, or cumulative water use. That makes the display more informative than a basic timer when you want to measure water volume as well as run time.

To change between gallons and liters, long-press the button while viewing flow rate. In another mode, a long press resets the data, so select the display you need before holding the button. The LCD automatically goes to sleep after one minute without operation or water flow. Keep hands dry when opening the battery compartment, insert the CR2032 in the correct direction, and lock the compartment securely. Buyers often praise the meters’ usability and perceived accuracy, feedback on durability and waterproof performance is mixed, while the product is rated IPX6.

What you get

This is a two-meter pack, a practical format for monitoring two hose locations or keeping one meter available for a separate watering or tank-filling task. The meters use 3/4” NH connections, with a female inlet and male outlet on each unit. A CR2032 battery is included.

Questions before you buy

Will it connect to my hose? The meter has a 3/4” NH female inlet and a 3/4” NH male outlet. Match these thread types to the hose or faucet connection in your setup.

Can I view water use in liters? Yes. The display switches between US gallons and liters with a long press while in flow-rate mode. The current flow can be shown in GPM or L/min.

What does the display measure? It offers four views: real-time flow rate, consumption from the last use, a daily average for a week, and total water consumption. The weekly average count starts the next day.

Buying verdict

For anyone who needs more than an estimate of hose run time, the O-WM-2P combines live flow readings with several consumption records in a two-meter set. Its brass 3/4” NH connections and selectable gallon or liter display make it a useful fit for garden watering, sprinkler lines, and RV tank filling where tracking water volume matters.
