This water meter can be used for family or apartment to measure the water consumed. It is stable and energy-saving, can be used for a long time. The AMR system is new LONG DISTANCE CONTROL SYSTEM (LDCS) of water charge and management system for water companies. This system consists of water meter, collector, GPRS concentrator and Teminal Processor (TP). By using Zig-Bee communication and GPRS to make the water charge management automatic and intelligent.
1. Low-consumption design. Only consuing when reading.
2. Valve control remote switch, No need tattery.
3. Combined with meter-reading system to AMR.
4. Electronic direct-reading meter with high-definition LCD display can reads and sends digital information directly.
5. High sensitivity electronic meter with low starting flow measurement, high precision measurement and automatic error correction function.
6. Low power consumption, normal working can be power supplied by M-BUS /RS 485 communication ports line.
7. Measuring maintains for 5 years power supplied by backup internal battery when communication ports line is broken.
Maximum permissible error:
1. From the minimum flow-rate (Q1) inclusive to the lower zone of the transitional flow-rate (Q2) exclusive: ± 5%.
2. Water temperature ≤ 30° C from transitional flow-rate (Q2) inclusive to the higher zone of the maximum flow-rate (Q4) exclusive: ± 2%. (hot water meter >30° C± 3%)
