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.

Disadvantages of other types of meters:

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.

Why CDMA?

Wide coverage

1.Distribution of telecom base stations is wider

2.Frequency of Telecom CDMA is 800MHz

GSM working frequency - China Mobile (Upstream 885-909, Downstream 930-954)
GSM working frequency - China Unicom（Upstream 909-915, Downstream 954-960）

CDMA working frequency - China Telecom (Upstream 825-835, Downstream 870-880)

Low Power Consumption

1.Power consumption of CDMA module is up to 600mA

2.Lower demand on battery capacity

Maximum consumption of GPRS module is about 1.8A

Excellent Service offered

1. Well-equipped infrastructure from Telecom

2. Strategic cooperation agreement signed with Telecom
