External Dimension：

Common Feature：

1. Water meter belonging to IOT type 

2. Electromechanical separation structure

3. Base meters can be interoperable.

4. Adopt non-magnetic, Hall, and photoelectric acquisition technology

Overview of Ⅰ-type-NB-IoT ：

Narrow-band IOT water meter is a new type of intelligent water meter based on NB-IoT communication technology. It applies NB-IOT technology to collect, transmit and control water meter data. Water quantity data is transmitted to background server and client to realize remote data transmission and remote control. It can realize real-time monitoring of water meter’s water consumption information, and realize reading of total water consumption. Water meter valve can be remotely controlled to monitor water consumption in real time. This product can improve stability and reliability of water meter data transmission, reduce communication cost of the product, enhance intelligent terminal function of data acquisition of water meter, and greatly improve meter reading efficiency.

Product Feature：

1. Product is featured with low power consumption and uses ER34615 (19AH) battery lasting for more than 6 years.

2. It is applicable to complicated environment due to its high transmission sensitivity, and strong signal. 

3. It can operate independently and does not need to be equipped with acquisition equipment.

4. It adopts GPRS technology to ensure high capacity of unit area.

5. It’s easy and fast to set the parameters of handheld meter reader or software.

6. It can realize prepayment function, can open and close valve through background remote control.  

Overview of Ⅱ-type-GPRS：

IOT water meter realizes automatic remote meter reading through GPRS mobile network, and it applies GPRS technology to collect, transmit and control water meter and actively upload its data on a daily basis. The data includes all 24-hour data of the same day (data interval is one hour), and it’s available to realize break-point continuous transmission. 15 days of historical data can be stored in water meter. The software provides continuous water consumption curve data, which provides strong technical support for scientific water consumption flow and analysis upon water consumption fluctuation. GPRS water meter also has the function of automatically detecting battery status and operating data to ensure stability.

Overview of Ⅲ-type-GPRS：

This product is a type of rotor, multiple-jet, wireless remote water meter used for measuring the total volume of drinking cold water flowing through tap water pipelines. It adopts the materials that meet the hygienic standard of drinking water measuring meter materials, and all performance indexes conform to the technical requirements of GB / T778-2007 (equivalent to ISO4064), CJ / T188-2004 Technical Conditions for Data Transmission of Household Meters issued by the Ministry of construction, DLT645-2007 Communication Protocol for Multifunctional Electric Energy Meters issued by the Ministry of Electric Power, and CJ / T244-2012 Electronic Remote Water Meters. It can be used to measure and charge the water consumption of residential houses, enterprises, and public institutions. It serves as an ideal metering and charging instrument for modern management in tap water charging management departments, such as water supply companies and real estate property companies etc.

Feature：

1. The system adopts reliable meshed topology structure.

2. The router has maximum 8 series network, and it can accommodate 1024 nodes at most. The logical address of modules adopts the ID of 4-byte table.

3. SD_ WLM network can automatically optimize network routing, automatically discover and delete nodes. For nodes that malfunction, WMRNET has automatic recognition function, being able to automatically repair routing.

4. SD_WLM wireless network module adopts the high-performance RF chips of US SEMTECH Company. Its maximum transmitting power reaches 20dBm and the maximum receiving sensitivity is -148dBm.

5. SD_ WLM combines with low power consumption and suitable communication rate. Optimal transmitting power is 17dBm, receiving sensitivity is -125dBm, and air transmitting baud rate is 4.56Kbps. The communication distance between modules reaches 1200m-1500m.

6. Numerical value of every meter can be read at 0.25S by means of SD_ WLM direct-reading, with fast network construction, quick speed-reading, and high success rate of one-time meter reading.

7. For system networking, ADHOC wireless structure is adopted within residential quarters, while GPRS data transmission structure is adopted outside.

8. The system adopts GPRS remote meter reading, wireless meter reading by handheld meter reader, and on-site numerical meter reading.

9. The whole system is powered by AC or battery, being safe, reliable, and easy to install.
