The difference between wired remote water meters and wireless remote water meters
Water meters are essential in our daily lives. On the market, they are broadly categorized into wired remote-read water meters and wireless remote-read water meters. Although the two types differ by just one character, they have significant differences in terms of functionality and usage. Let’s take a closer look at the distinctions between wired and wireless remote-read water meters.
First, let’s understand how a water meter works: Since the meter’s outer casing is fixed, its internal volume remains constant. As water flows through the meter, it sets a turbine wheel in motion. Each time the turbine wheel rotates once, a precisely measured volume of water passes through the meter. Therefore, by accumulating the number of rotations of the turbine wheel and multiplying that number by the fixed volume of each rotation, we can determine the total amount of water that has flowed through the meter. The meter body features an integrated design that enables real-time recording and storage of the user’s water consumption. Each water meter is assigned a unique code; when a smart water meter receives a meter-reading instruction, it can immediately upload the meter data to the management system.
A wired remote water meter is a type of remote water meter that relies on wired cables for data transmission and is typically used in locations where cable installation is convenient. Generally, wired remote transmission systems can be categorized into three types based on their communication protocols: RS-485, 1775m bus, and PLC. While these wired remote water meters tend to be relatively inexpensive, they are prone to getting blocked during installation and wiring processes. Due to the renovation of older residential communities, many apartment buildings have already been fully renovated, requiring new holes to be drilled and wiring to be reinstalled. This often leads to resident dissatisfaction and significantly increases the difficulty of construction work.
Nevertheless, this remains the most mainstream product available today. On the other hand, wireless remote water meters are built on the basis of conventional water meters and equipped with a dedicated low-power transceiver module, enabling wireless transmission of meter readings and other data as well as reception of commands and execution of corresponding operational actions. The wireless remote water meter communicates exclusively with the collector. After system installation, the meter’s association with a specific collector is determined based on the collector’s installation and commissioning status; once this association is established, it cannot be altered, thereby ensuring unified and coordinated management of wireless communications.
Above is a comparison of wired remote water meters and wireless remote water meters, along with related information. I hope this has answered your questions and been helpful to you.

Longzhida Company Successfully Hosted the Victory Parade Commemorating the War of Resistance.
Today is a day that every Chinese person should solemnly remember—the 80th anniversary of the victory of the Chinese People’s War of Resistance Against Japanese Aggression and the World Anti-Fascist War.
On July 2, Chengde Longzhida Company held a meeting with the Sino-German Institute. After thorough discussions between the two sides, Mr. Bai, General Manager of Longzhida Company, and the faculty team from the Sino-German Institute reached a consensus: Longzhida Company officially entrusted the Sino-German Institute to carry out the design and R&D work for a new type of ultrasonic water meter.
On May 30, Longzhida Company successfully held an exceptionally meaningful event titled “Welcoming the Eighth ‘National Science and Technology Workers’ Day’: Promoting the Spirit of Scientists.”
