Wireless remote reading water meter multi jet dry dia | valve control, DN15 - DN25 Iron housing
Using method
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, 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 open environment. Each piece of concentrator can manage 255 pieces of collector maximumly.
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
- The microprocessor adopts nanowatt technology, with wide working pressure and low power consumption, the inner EEPROM can rewrite for more than 100,000 times.
- Data hold and restoration function: the data in the water meter can be stored for ten years when there is no power, when the power on, with the data restoration function, the data can be read back by devices.
- Replaceable battery design, replace by user self. Easy maintenance.
- The mechanical display is clear for reading, and the base meter can be used for 10 years.
- Each meter has a unique ID No., and has complete production, debugging, usage and maintenance record
Key features
- Adopt wireless communication technique to transmit data, thus no need of communication cable layout, and reduce the installation cost greatly.
- Electric floating ball valve technique: adopt electric ball valve technique, work reliably and lower loss of pressure.
- 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.
- Anti-attack of strong electricity or magnetism: water meter will give alarm when being attacked by strong electricity or magnetism.
- Micro-computer and microstorage technique: high integrated and high reliability.

Installation
- The installation of water meter meets the installation requirements of ISO4064-2:2005
- The caliber of water meter shall correspond with caliber of pipes and the used flow rate is less than or close to the permanent flowrate. The installation place should avoid exposure, flooding, freeze and pollution, and convenient for installing, removing and reading data.
- The water meter shall be installed horizontally (display surface is upward).
- The sands and stones and other sundries in the pipelines shall be cleared.
- The arrow on the water meter should be the same as the water flow in the pipeline.
- If the water meter is installed on the inlet of the boiler, it is better to install inverted valve on the outlet of water to prevent the return current of hot water and steam will damage the water meter.
Competitive Advantage:
- Compliance to international standards: ISO4064 / GBT778 / Q/320700JR05-2003
- Strict process control
- Advanced calibration equipment
- Engineer team
