Your benefits
- Best in class accuracy and repeatability up to R1000
Accurate low-flow measurements and ondemand leakage notification. Reduces nonrevenue water and scarcity water. - Accurate measurements in all possible directions and installation conditions
High installation flexibility reduces installation costs. - Integrated LoRaWAN over wMBus dual mode and seamless data integration
Reduction of network initialization, maintenance, and meter reading costs. - Over the air software update to upgrade new features or radio settings and to increase lifetime
Sustainable design and extendend product life time.
Applications
- Cold water supply systems (water temperature up to 50 °C) requiring reliable and accurate water consumption metering
- Reliable data communication on site (NFC) and integrated radio technology (RF) for mobile or fixed network / smart metering collection systems (AMR)

R1000 accuracy measurements
GWF 4D-Technology delivers best in class measuring range and repeatability.
Pressure loss curve
The clean and homogenous measuring channel results in best in class head loss.
Display information
The display is updated every second and shows beside the WELMEC information the following content:
| 1. Volume unit indicator (digital) | 8. Test mode information |
| 2. Non-billing relevant lines | 9. Air in pipe icon |
| 3. Volume | 10. System alarm icon |
| 4. Tariff zone | 11. Battery level symbol |
| 5. Main flow direction (automatic set) | 12. Actual flow direction arrow |
| 6. Radio connection status | 13. Flow rate |
| 7. Leakage indicator | 14. Flow rate unit indicator (digital) |
Configurable alerts
The following integrated alerts are displayed on the meter LCD and transmitted over the integrated radio or NFC interface.
Metrology alerts:
- Water leak
- Water burst
- Air in pipe
- Empty pipe
- Reverse flow over configured time or volume
- No flow over configured time or volume
- Tampering
- Ambient temperature too high or low
- Water temperature too high or low
- Low battery
Communication alerts:
- NFC error
- Invalid configuration
Interal data backup and security
The meter has a permanent memory, in which more than 400 log's are saved. The data logging interval is configurable and results in the following history log periode:
| History log period | Data logging interval |
|---|---|
| 4 days | 15 min |
| 16 days | 1 heour |
| 400 days | 1 day |
| 20 years | 1 month |
Each logging interval backup's the following data:
1. Cumulative, forward and reverse volume
2. All possible active alerts
3. Max. and min. flow rates incl. timestamp
4. Max. and min. temperatures incl. timestamp
The monthly/yearly log is written on the first day of the month/year, the daily log at midnight.
