HOW TO USE
The wireless remote meter-reading water meter system consists of wireless remote water meter, collector, concentrator and management software.
1. Bottom layer communication: Bottom layer communication means communication between the collector and water meter. Wireless network signal has the positive of wide signal propagation,
wide coverage area ability and fast construction.
2. Middle layer communication: Middle layer communication means the communication between the concentrator and collector. This communication is by wireless RF way, no need of communication line. The wireless communication distance between the concentrator and
collector can be about 3km at wide open area. Each piece of concentrator can
manage 255 pieces of collector.
3. Upper layer communication: Communication methods indicate below can be selected between concentrator and management center.
(a) GPRS Communication Mode
(b)Telephone Line Communication Mode
(c) RS232 Communication Mode
(d) Ethernet Communication Mode
FUNCTIONS
1. The microprocessor adopts
Nano watt technology, with wide working pressure and low power consumption, and
the inner EEPROM can rewrite for more than 100,000 times.
2. Data storage and recovery
function: the data in the water meter can be stored for ten years when battery
is dead, and the data can be recovered when power is back.
3. Replaceable
battery design, replace by customer. Easy maintenance.
4. The register
is easy to read, and meter lifetime more than 10 years.
5. Each meter has a unique ID No., and has complete production, debugging, usage and maintenance record.

INSTALLATION
1. The installation of water meter should meet the installation requirements of GB/T 778.2-2007 part 2: installation requirements.
2.The caliber
of water meter shall be based on the size of the pipeline and the usual used
water flow is no more than common flow of the water meter; and the installation
location shall be avoided insolation, flooding, freezing and pollution, and
convenient for installation, removing and reading data.
3. The water meter shall be installed
horizontally (display surface is upward).
4. The sands and stones and other
sundries in the pipelines shall be cleared.
5. The arrow on the water meter should
be the same as the water flow in the pipeline.
6. The installation place of water
meter should be far from the appliances with strong electromagnetic
interference, such as air condition compressor, induction cooker, and should
avoid a metal box and surrounding by metal objects.
7. If the water meter is installed on
the inlet of the boiler, shall install check valve on the outlet of water to
prevent the return current of hot water and steam from damaging the water
meter.
DIMENSION

Note:
L1---Length of the water meter
L2---Length of the meter and the joints
L3---Effective length of the threaded connection
H---Height of the water meter
W---Width of the water meter
MAIN TECHNIQUES
1. Adopt wireless communication technique to transmit data, thus no need of communication cable layout, and reduce the installation cost greatly.
2.
Electric floating ball valve technique: adopt electric ball valve technique,
work reliably and lower loss of pressure.
3. Totally sealed design: all the
circuits are sealed by high performance casting glue, so there is no exposed
electrode, and can be used in moist environment.
4.
Anti-attack of strong electricity or magnetism: water meter will alarm when
being attacked by strong electricity or magnetism.
5.
Micro-computer and micro-storage technique: high integrated and high
reliability.
