NB IoT IoT water meter, IoT remote water meter, NB water meter

NB IoT IoT water meter is an intelligent water meter used for remote meter reading and valve control. Adopting the most advanced narrowband cellular network communication technology in the world, it has the advantages of deep network coverage, wide links, low power consumption, and stable, reliable, and secure communication. It communicates remotely with servers through Narrowband Internet of Things (NB IoT) without the need for collectors or concentrators. It adopts a point-to-point connection method of one meter and one card, simplifying equipment installation and achieving automatic remote meter reading of water meter usage. Its signal network has deep coverage (underground meter wells, pipeline wells, etc. can all be used normally), ultra-low power consumption, stable and reliable communication, and uses authorized narrowband 4G network transmission without the need to build base stations. Data is uploaded and saved through the network company's communication base station. And it effectively avoids the manual work of on-site meter reading by the management department. The device adopts fully sealed technology and industrial grade SIM card can achieve remote reading Remote valve control warning system: Alarm prompts for battery undervoltage, abnormal metering, etc. Ultra long life combination battery; High accuracy of battery built-in/external antenna sampling: Based on our module optoelectronics, Hall sensor, reed switch, and magnetic switch sampling for water meter remote transmission, the reading accuracy can reach 100%. Scheduled data upload - manual data upload: retransmission times: 16 times. Support multiple payment methods of WeChat or Alipay.

II Functional Features

2.1 Flow measurement

The NB water meter has two pairs of pulse signal detection ports. By detecting the pulse signals of the two ports and setting the pulse equivalent, the current flow value can be calculated and stored, and the accumulated flow, settlement day flow, and last month flow value can be recorded.

NB water meters perform anti shake processing when detecting pulse signals, which can effectively avoid false measurement caused by external interference and improve measurement accuracy. At the same time, the water meter also has a pulse signal anomaly detection function, which can detect pulse signal faults and strong magnetic interference, and record abnormal states.
