IoT (Internet of
Things) Wireless AMR/AMI Water Meter
The IoT
water meter refers to the AMR/AMI water meter that uses private network of
internet of things, it is the new generation remote reading water meter. It
features low overall cost, particularly, the low installation cost. Just as
normal mechanical water meters, no on-site operations like drilling or wiring
required. The meters work after they are installed on the pipe line. All
debugging completed at the computer terminal. The IoT water meter simplifies the
system. It can be judged as issue of meter itself when malfunction arises which
makes failure diagnosis easier. It makes itself easier to work by removing
intermediate links that can reduce the maintenance and operating cost to the
lowest level.
1. Mechanical Water Meter
Manually meter reading is required, time
& labor-consuming, high error rate.
2. RF (Radio Frequency) Smart
Water Meter
Hard to find malfunctions when they arise
3. Photoelectric Direct – Reading
AMR/AMI Water Meter
Wiring is required for AMR/AMI application, installation
cost is high.
The
presence of IoT water meter solves all the above disadvantages, it transfers
data to the service platform (data center) wirelessly, no need to do wiring job
when installation, is able to receive command from the data center in real time
that drastically improves the real-time operability of subscribers.

built-in antenna design that guarantee IP68 protection class of the product.
5. Stepped tariffs that is realized
directly on meters .
6. High definition segment LCD display,
real time display of subscriber data, water meter status etc.
7. Storage of 18 months of historical data
information.
8. Valve auto close protection when magnetic
interference, power down, undervoltage of battery is detected.
9. Remote control function, is able to
remotely open/close the valve of meter.
10. Supports flexible methods of payment by
top-up at water utility, bank, collecting sites, even by WeChat, etc.
11. Use of management center of B/S
structure, is able to monitor the running status of meters at any time that
improves the working efficiency of management department.
12. GPS
physical positioning and query
IoT (GPRS) Water Meters
1. Use
