Product Description

Brief introduction
The Internet of Things remote water meter is a remote water meter developed for the remote management of meter reading and control. It adopts our direct reading water meter as the basis of measurement, and automatically communicates via GPRS to realize automatic remote meter reading of water meter usage, which effectively avoids the management department's on-site meter reading. This product also has a valve control function (optional), which is convenient for the management department to control the water usage of the water meter, making remote meter reading and control more convenient and reliable, while saving manpower, material resources and financial resources. Long

Nb IoT water meter features
NB IoT water meter:
1.Remote networking, meter data can be collected in any GPRS signal coverage area, no longer be limited by the distance
2.Each meter is directly connected to the server, does not need to go through the collection device, and the transmission is safe and reliable.
3.Ultra long life combination battery: battery capacitor combination power supply guarantees 8 years of use without replacement
4.The meter reading personnel remotely read the value of the meter at the water meter through GPRS to realize the functions of metering, protection, and control of valves.
5.With valve installed, the system has a remote control valve function.

Communication Band	None	470-510Mhz 865-868Mhz	GSM850/EGSM900	CDMA1X800E/EGSM900
Advantage	Transmit information through IC card, charge accurately Install and operate easily	LAN transmission data, low power, Suitable for intensive installation real-time reading control	Wide area network, data transmission without distance limitation, simple installation and debugging, low sample order cost.	Wide coverage, low power consumption, low cost and slower rate.
Limitations	The stand-alone version of the software can only be read and controlled on a designated computer. Back up user data when replacing a pc.	Greater impacts by obstacles and limited communication distance(up to 1 km).On-site debugging is a heavy workload	Occasionally there will be data packet loss, high transmission rate, relatively high power consumption.	At present, NB technology is not fully mature and the coverage of base stations is low.
