- Connecting to Watering Device:
Connect your garden hose, sprinkler, or nozzle sprayer to the 3/4" NH thread brass outlet of the flow meter. Ensure all connections are tight to prevent leaks.
Operating Instructions
The RESTMO Water Flow Meter features an intuitive LCD screen and a single push button for easy operation and mode selection.
Measurement Modes:
Short press the control button to cycle through the four available measurement modes:

1. FLOW Mode:
Displays the real-time water flow rate (e.g., GAL/Min). This mode is useful for monitoring the current rate of water usage.
To switch units (gallon to liter) in FLOW mode, long press the control button.
2. CONSUMPTION Mode:
Displays the last-time water usage (e.g., GAL). This shows the total amount of water consumed during the most recent watering session.
3. AVERAGE Mode:
Displays the daily average water usage of a week (e.g., GAL/D). The calculation starts from the next day after initial use. This helps track average consumption over time.
4. TOTAL Mode:
Displays the total accumulated water usage (e.g., GAL). This mode keeps a running total of all water passed through the meter.
Resetting Data:
To reset data in CONSUMPTION, AVERAGE, or TOTAL modes, long press the control button while in the desired mode. This will clear the displayed value for that specific mode.
Automatic Sleep Function:
The LCD screen will automatically go to sleep if there is no operation or water flow detected for 1 minute to conserve battery life. The display will reactivate upon water flow or button press.
Maintenance
Proper maintenance ensures the longevity and accuracy of your RESTMO Water Flow Meter.
- Cleaning: Wipe the exterior of the meter with a soft, damp cloth. Avoid using harsh chemicals or abrasive cleaners that could damage the display or housing.
- Weather Resistance: The meter is designed with IPX6 waterproof grade and rugged ABS material to resist UV, sunshine, and rain. While durable, prolonged exposure to extreme weather conditions should be minimized if possible to extend product life.
- Battery Care: As noted in setup, always ensure hands are dry when handling the battery compartment. Replace batteries as needed to maintain optimal performance.
- Storage: If storing the meter for an extended period, especially during freezing temperatures, it is recommended to remove the battery and store the unit in a dry, protected area to prevent damage from freezing water or battery leakage.
Troubleshooting
If you encounter issues with your RESTMO Water Flow Meter, consider the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| Display is blank or dim. | Low or dead battery; incorrect battery insertion. | Replace the battery with a fresh one, ensuring correct polarity. Make sure the battery compartment is securely locked. |
| Inaccurate readings. | Obstruction in flow path; sensor malfunction; extreme water pressure fluctuations. | Check for any debris in the meter's inlet or outlet. Ensure water flow is consistent. The meter has a measurement tolerance of less than 5%. |
| Water leakage from connections. | Loose connections; damaged O-rings or threads. | Ensure all connections are tightened securely. Check the condition of rubber washers or O-rings and replace if damaged. |
| Meter not registering flow. | Insufficient water flow; impeller stuck. | Ensure adequate water pressure. Check if the internal impeller is free to spin. |
If problems persist after attempting these solutions, please contact Restmo customer support.
