summary:

NB IoT/GPRS IoT remote direct reading water meter (hereinafter referred to as IoT water meter) is a remote water meter developed by our company for easy remote meter reading and control. Electronic reading is based on direct reading sampling technology, and through NB IoT/GPRS network communication, it realizes automatic remote transmission of water meter usage, effectively avoiding the need for management departments to come to the door for meter reading. It has valve control function (optional), which facilitates management departments to control the water meter usage, making remote meter reading and control more convenient and reliable. While saving manpower, material resources, and financial resources, it effectively improves production efficiency, especially suitable for installation in environments with difficult wiring and sparse population.

This IoT water meter complies withGB/T778-2007Measurement of Water Flow in Closed Full Pipelines - Drinking Cold Water Meter and Hot Water MeterCJ/T224-2012Technical requirements for electronic remote water meter. Communication protocol compliance《130Communication Protocol Specification《GB4208-2008The protection level specified in the standard regulationsIP68.

Core functions： 1Remote reading: Proactively report readings on a periodic basis. 2Remote valve control: can remotely close and open valves. 3Prepaid: Supports prepaid and pre order quantities, and closes the valve for overdue payments. 4Warning system: Alarm prompts such as battery undervoltage, abnormal measurement, pre order quantity and prepaid usage reaching threshold, etc., can be set according to different users for different emergency water usage. 5Large capacity storage: can last up to24Freeze data for months and months31Freeze data on a daily basis. 6Step by step water price: Water prices can be set at different benchmark prices and step by step prices based on user categories and usage.

Performance advantages:

■Ultra long life combination battery: The battery capacitor combination power supply guarantees 8 years of use without replacement.

■Internal/External Antennas: Supports both internal and external antennas, with stable and reliable signals, achieving full coverage and no blind spots.

■High accuracy of direct reading sampling: Based on our company's direct reading water meter remote transmission, the reading accuracy can reach 100%.

■Flexible upload frequency setting: The data upload cycle can be set to meet the management needs of different users.

■Protection level IP68: Complies with the international standard IEC529 for protection level IP68.

■Patent for replaceable battery structure design: The battery box adopts an independent replaceable design, without the need to open the main body cover, making replacement convenient.

■8 years of communication fees: The meter includes 8 years of communication fees when it leaves the factory.

■The system adopts BS architecture: both PC and mobile phones can support it.

The function of the main components:

■Power supply battery: mainly used for storing batteries for disassembly.

■GPRS antenna: mainly used to place GPRS module antenna.

■Case: mainly used to install measurement and acquisition modules, circuit boards, and valve control motors inside.

■Optoelectronic direct reading sampling module: mainly used for sampling measurement data.

■Base meter: mainly used to measure current water consumption.

■Through hole ball valve (optional): mainly used to control the closing and opening of tap water flowing through the meter under the control of the main circuit board.
