What Is the Difference Between Wired Remote Water Meter and Wireless Remote Water Meter?
One of the main reasons why the intelligent remote water meter can quickly replace the traditional mechanical water meter is that it can realize the remote collection, data storage, and transmission of the water meter information to the meter reading system through the electronic module. At present, the smart remote water meters on the domestic market are mainly divided into wired remote water meters and wireless remote water meters. Wired remote water meters are common with photoelectric direct reading remote water meters. The best sales of wireless remote water meters in recent years are NB-IoT wireless remote transmission and LoRa wireless remote transmission. So, what are the differences between wired and wireless remote water meters? How can users choose the appropriate transmission method according to their own needs?
Wired and wireless here refers to whether the communication method of a smart water meter to realize data transmission requires the use of cables.
Communication plan composition:
(1) Wired remote water meter: The photoelectric direct reading remote water meter adopts M-Bus and RS-485 bus communication. This kind of communication needs to connect multiple water meters to the concentrator through cables, and then transmit the collected water meter data to the main station system through the concentrator.
(2) Wireless remote water meter: Both NB-IoT and LoRa directly transmit the data of the water meter measurement product to the base station through the wireless transceiver module to realize remote meter reading.
Advantages and applicable scenarios:
(1) Wired remote water meter: M-Bus water meter can be used directly. The hardware cost of the water meter is relatively low, and the data transmission by the cable is stable and fast. It is suitable for application environments with a small number of water meters and concentrated installations, such as rental houses/hotel apartments.
(2) Wireless remote water meter: Using wireless transmission technology, no wiring is required, it can be installed quickly, and the cost of transformation is low. It is suitable for environments where the owners are scattered, the distance is long, the number of meters is large, and the real-time data requirements are high. Such as factories, villas, and shopping centers.
The main difference between the two is the above. But no matter whether it is wired or wireless, the functions of the two with the meter reading system are the same, which can realize the functions of remote cost water meter data, remote check balance and payment, timing automatic valve switch, bill check, and other functions. Both have their own advantages, which can make remote meter reading and control healthier and more reliable, and effectively improve productivity while saving manpower, material, and financial resources. Therefore, users can choose the most suitable one according to their own situation.
