2. Setup
2.1 Battery Installation
The water flow meter requires a CR2032 lithium battery. To install or replace the battery:
- Locate the battery compartment on the back of the device.
- Use a coin or the included circle sheet to twist and unlock the battery cover.
- Insert the CR2032 battery with the positive (+) side facing up.
- Replace the battery cover and twist to lock it securely, ensuring a waterproof seal.
2.2 Connecting the Water Flow Meter
The RESTMO Water Flow Meter features a 360° rotating inlet and 3/4" NH hose threads, making it compatible with all standard outdoor faucets and garden hoses without requiring additional adapters.
- Ensure the water source is turned off.
- Screw the inlet (top part with the brass connector) of the water flow meter onto your outdoor faucet or the end of your garden hose. Hand-tighten only.
- Connect your garden hose, nozzle, or sprinkler to the outlet (bottom part) of the water flow meter. Hand-tighten only.
- Ensure all connections are secure to prevent leaks. Teflon tape can be used for a tighter seal if necessary.
3. Operating Instructions

4. Maintenance
4.1 Cleaning the Filter Washer
The water flow meter includes a metal filter washer at the inlet to prevent dirty, sediment, and other larger particles from entering the device and affecting measurement accuracy. Regularly check and clean this filter to ensure optimal performance.
4.2 Weather Resistance
The device has an IPX6 waterproof grade, ensuring stability for outdoor use and resistance to UV, sunshine, and rain. However, it is recommended to store the device indoors during extreme weather conditions or prolonged periods of non-use to extend its lifespan.
5. Troubleshooting
- No Display: Check if the battery is correctly installed and has sufficient charge. Replace the CR2032 battery if needed.
- Inaccurate Readings: Ensure the metal filter washer is clean and free of debris. Verify that all connections are tight and there are no leaks. Ensure water flow is consistent and not excessively turbulent.
- Leaks at Connections: Hand-tighten all connections. If leaks persist, apply Teflon tape to the threads. Ensure rubber washers are properly seated.
- Screen Not Responding: Try removing and reinserting the battery to perform a soft reset.
