Brief Introduction:
This kind of NB-IoT water meter is the latest generation of remote water meter that application of mobile network remote water meter,.One of its remarkable characteristics is that its comprehensive cost is very low, especially the installation cost, just like the ordinary mechanism water meter, no need for perforation, wiring and other field operations, only install on the pipeline can run. Operators finish all debugging entirely on the computer terminal, and the product is easy to promote widely. The cost of using Internet of things water meters is also lower than that of traditional smart meters. In the old mode, data transmission needs four links: data line, handheld machine, repeater and concentrator. Any problem in any link will lead to batch error, and its installation and maintenance requirements are high. And IoT water meters feature a simple structure with no intermediate links between the water meter terminal and the cloud. Any fault only occurs on the water meter itself, and users can minimize maintenance and operation costs.NB-IoT Water Meter
NB-IoT water meters adopts a modular electromechanical separation design. The mechanical metering section and the data transmission section feature full modularization and allow flexible combined installation.
The Main Function Introduction:
| Name | Resume | Parameter | |
| 1 | Measurement | Use of magnetic or Non-magnetic sensor measurement signals | |
| 2 | The management of water meter No. | Unique identification number for each water meter | Available for users to use 8-bit numbers |
| 3 | Initialization | Zeroing the metering data of the instrument.Restore all parameters to default values | |
| 4 | Correction Time | Without a leap year problem,can be calibrated at any time | From 2000 to 2100,Min. correctable to seconds |
| 5 | Battery voltage detection | When the battery voltage reaches the lower limit, it can make an alarm prompt. | |
| 6 | Remote diagnosis | Forward cumulant, reverse cumulant,residual amount, current instantaneous flow,battery status and other alarm information. | |
| 7 | NB Fixed Time opening | Turn on the NB power at some time | Range:0:0-23:59 |
| NB Interval opening | Turn on the NB power supply every interval | Range: 10 minutes to 1440 minutes | |
| NB Quantitative opening | The system activates the NB power supply at each interval based on water consumption. | This function is temporarily unavailable | |
| NB fault alarm on | Turn on NB power supply when NB Water meter has system failure or monitoring abnormal water use | ||
| NB Overtime | 80 seconds by default, not less than 80 seconds | ||
| NB transmission period | The default 0 / 24 is working hours | ||
| 8 | Read module production batch No. | Including module production batch No,software version, software compilation time,several compilations, etc. | |
| 9 | Read parameters | Read out the parameters in the water meter at any time, including: program version, NB parameters, working mode, etc. |
