NB-IOT Remote Reading Wireless Smart Water Meter
The STW36-N Smart Remote Reading water meter adopts the advanced NB-IOT(Internet of Things) communication technology, Through microelectronic control circuits, it converts the pulse signals of traditional mechanical meter into electrical signals. Then the metering data is transmitted to background platform through NB-IOT network automatically.Our water meters comply with STS, ISO 9001 and ISO14001 regulations.They are used to measure the volume of cold water through a pipe. Because it can be connected to the main system, we can query a lot of information, such as: total water consumption, total purchase, water surplus, etc.
NB-IoT is Narrow Brand Internet of Things. It is built in cellular network and consumes only about 180kHz bandwidth. It can be directly deployed in GSM network, UMTS network or LTE network to reduce the deployment cost and achieve smooth upgrade.The NB-IoT communication module has extensive coverage, the ability to support connections, lower power consumption, and an extremely long service life.Therefore, it has become the preferred communication module for many users.
IB-IOT water meters also have the following advantages:
1. Site-free wiring construction, saving manpower and material resources.
2. No additional network equipment, the scene without 220V power supply.
3. Operation and maintenance without professional knowledge, replacement is very convenient.
4. Built-in networking module, communicate directly with the server, without any intermediate links, communications fast, reliable and stable.
5. More suitable for renovation of old buildings.
Features:
1. Ingress IP68 waterproof protection
2. Up to 8 years battery life
3. Automatic valve controlling
4. STS standard
5. Real time o-clock
6. Utilities can set step price into meter on request
7. Anti-Tamper Magnetic field protection
8. RF-LoRa communication(optional)
9. Pay by mobile payment M-PESA, Alipay, MTN, Airtel, etc
