Woltman water meter with removable dial register, RF type IC card prepayment water meter DN50
The basic water meter Features:
- The Nominal flowrate of Qn 1.5 m³/h to 15m³/h, Q3 2.5m³/h to 25m³/h
- R value is R80 / 100 / 125 / 160 as requested
- Suitable for both cold and warm water applications
- Replaceable meter inserts available
- Good readability even at extreme operational conditions
- Optionally retrofittable with pulse contactors
Water meter operate condition:
- Water temperature:0.1℃～40℃ for cold water
30℃～90℃ for hot water meter. - Water pressure: ≤1.0 Mpa
Note:
- Measuring accuracy conform to ISO 4064 class B standard..
- Available with different length on request. Available in hot water meter on request.
Maximum Permissible Error:
(1) Between qt (included) and qs is ±2%;
(2) Between qmin and qt (excluded) is ±5%.
AMR System description:
1) Up transfer:
From concentrator to AMR control center.
(a) GPRS Communication Mode
(b)Telephone Line Communication Mode
(c) RS232 Communication Mode
(d) Ethernet Communication Mode
2) Down transfer
From the collector and water meter.
Wireless network signal has the positive of wide signal propagation, wide coverage area ability, fast construction. One piece of collector can connect with 128 pieces of meter maximally.
