How To Quickly Choose A Hydropower Remote Meter Reading Solution？（2）
Next, we will introduce the remote meter reading solution for water meters.
1. M-Bus meter reading solution
This solution is composed of converter, M-Bus water meter and concentrator. The data transmitted by the M-Bus water meter is converted through the converter, and then transmitted to the concentrator by NB/GPRS to realize remote automatic meter reading. The M-Bus water meter automatic meter reading solution has the advantages of strong reliability, fast data transmission speed, and stable communication signals. In terms of price, the M-Bus water meter is low in price, and one concentrator can connect 32 water meters. It is suitable for places that can be installed in a small area, such as apartments, school dormitories, and office buildings.
2. NB-IoT wireless IoT meter reading
The NB-IoT meter reading solution does not require wiring and is suitable for application environments where owners are scattered, far away, and require high real-time data. The solution is not limited by the installation distance of the water meter. If there is a base station at the installation location of the water meter, it can communicate with each other, and remote meter reading can be realized. Its advantages are strong signal, fast meter reading speed, meter reading data transmission does not exceed 1 second, and the execution switch valve delay does not exceed 2 seconds. The water meter has a large-capacity lithium battery, which has a large capacity that can be used for more than 10 years, low power consumption, and long life. It is suitable for the occasions where the meter is installed scattered and the distance is far away, such as villas, parks, and shops.
3. LoRa wireless meter reading
LoRa is a wireless communication technology dedicated to long-distance and low-power consumption, which is widely used in the field of long-distance low-rate IoT wireless communication in various occasions. It has the characteristics of small size, low power consumption, long transmission distance and strong anti-interference ability. There is no need to lay communication lines, and the water meter is powered by a built-in battery, and no power cord is required. With the Linshu intelligent debugging module, the meter can communicate.
The above are several different schemes for remote meter reading of water and electricity meters. A summary is that if your water and electricity meters are centrally installed, you can choose the M-Bus wired meter reading solution. For decentralized installation, NB-IoT/4G/LoRa wireless meter reading can be selected, and the carrier is not suitable for occasions with large power consumption loads.
