RESTMO Water Flow Meter with Brass Inlet

When watering runs longer than expected, it can be hard to tell how much water actually passed through the hose. The RESTMO water flow meter displays usage and flow rate to make that part easier to track.

Its brass inlet connects to an outdoor garden hose, and the LCD gives you several ways to view the reading.

That can help when watering a lawn, using a sprinkler or filling an RV water tank—without relying only on guesswork.

Highlights

The meter offers four display modes: real-time flow rate, last-use consumption, a daily average based on a week of use, and total water consumption. A short button press cycles through the modes. At the flow-rate display, a long press switches between US gallons and liters, in the other modes, a long press resets the data.

The LCD goes to sleep automatically after one minute without operation. The inlet is brass, while the meter has a heavy-duty ABS body described as weatherproof, UV-resistant and rated IPX6 for water protection. Those details suit outdoor hose use, though they do not make the device a substitute for monitoring water conditions elsewhere in the yard.

One practical example: while a sprinkler is running across the lawn, you can check the live flow rate, then use the consumption display to see how much water that watering session used. A basic timer can tell you how long the hose ran, this meter adds a water-volume reading.

How to use it

Attach the meter at the hose connection, then use the button to select the view you need. For a quick check while watering, Flow Mode shows the current rate. For a session total, Consumption Mode records the last use, Total Mode keeps a cumulative usage figure. The average mode tracks daily average water use over a week, starting its count the next day.

The specified measurable range is 0.3 to 12 GPM (1 to 45.5 LPM). The instructions recommend a moderate faucet setting for the best reading rather than opening it fully. Keep in mind that the device reports water flow and volume, not whether a plant or lawn needs watering. Without that measurement, use the readout to understand consumption rather than as a watering recommendation.

Practical tips

Choose the display before you start if you want to monitor one specific figure, and use the reset function in the appropriate mode when you need a fresh tracking period. Remember that a long press behaves differently depending on the screen: it changes units in Flow Mode and resets data in the other modes.

A solid pick if you want more than a run-time estimate and need to track hose-water use across garden watering or RV tank filling. It might not be a great match if you need readings outside the stated flow range or expect the meter to decide when watering is necessary. For a simpler setup, a timer may be enough, for measured water consumption, this meter gives you a more direct figure.

Before you decide

Can it show both flow rate and total water use? Yes. Flow Mode shows the real-time rate, while Total Mode displays total water usage.

Can I switch between gallons and liters? Yes. Long-press the button while in Flow Mode to change between US gallons and liters.

Does the display stay on continuously? No. It automatically goes to sleep after one minute without operation.

Should you buy it?

Choose the RESTMO if you want to see how much water a hose-based task uses, rather than estimating from time alone. Its four modes and unit switching make it useful for comparing a watering session with cumulative use, and the brass inlet and outdoor-rated construction fit the intended setting. Skip it if your needs fall beyond its stated flow range, or if you want guidance on plant watering rather than a meter for water passing through a hose.
