That kind of water meter is better.
Smart water meters have ushered in the smart era. They’re easy to install, intelligent and fast, and support mobile payments. Below are several types of water meters—so which smart water meter is better?
1. NB Non-magnetic Remote-Reading Water Meter
The non-magnetic remote water meter employs non-magnetic signal acquisition technology and features functions such as water volume measurement, flow rate determination, water flow direction detection, ambient temperature sensing, data storage, and remote transmission. It replaces the traditional mechanical meter’s mechanical counting mechanism with an independent impeller, achieving an exceptionally long service life. By utilizing hardware self-scanning technology, it effortlessly achieves an ideal low-power mode that consumes no water and requires no electricity.
2. Ultrasonic water meter
The ultrasonic remote water meter is used to measure and control the total volume of water flowing through tap water pipelines. This product features an aesthetically pleasing design, easy installation, accurate measurement, stable operation, strong resistance to fouling and corrosion, long service life, safety and reliability, and cost-effectiveness.
3. IC card water meter
Using a contactless IC card (radio-frequency card) as the medium, various types of information are input into the smart water meter. The smart water meter automatically opens the valve to supply water based on the amount of water purchased by the user. When the water quantity reaches the alarm threshold or is completely used up, the valve automatically closes, cutting off the water supply—thus achieving the goal of “pay first, use later.” Additionally, the meter can record its operational status and, via a microcomputer running system management software, display the meter’s operating conditions.
4.4G-CAT1 Water Meter
The ultrasonic remote water meter is designed to measure and control the total volume of water flowing through tap water pipelines and to transmit data remotely to a designated IoT platform. This product features an aesthetically pleasing appearance, easy installation, accurate measurement, stable operation, strong resistance to fouling and corrosion, long service life, high safety and reliability, cost-effectiveness, and convenient remote monitoring and viewing capabilities. It can be widely used in various water-metering facilities.

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.”
