Which is better, a card-insertion water meter or a card-swiping water meter?
As smart water meters gradually gain popularity, a wide variety of smart water meters have emerged in the market. Based on their card-reading methods, they can be categorized into card-insertion water meters and card-swiping water meters.
Next, let me introduce to you: Which is better—card-insertion water meters or card-swiping water meters?
A card-insertion water meter is a type of water meter that uses an IC card for reading. A card-swiping water meter, also known as a contactless smart water meter, works just like swiping a transit card when you ride the bus—simply swipe it once, and that’s it. At first glance, it might seem that card-swiping water meters are more convenient, but that’s not actually the case. A card-insertion water meter has a dedicated card slot; you simply insert the IC card into the slot, and the meter completes the reading automatically. This makes it particularly convenient for elderly users and children, among other consumer groups. From a technical standpoint, there’s no question of whether one type of meter—the card-insertion or the card-swiping—is more advanced than the other.
Chengde Longzhida Intelligent Instruments & Meter Technology Co., Ltd. has developed an IC-card water meter that uses a contactless IC card as its medium to input various types of information 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 volume reaches the alarm threshold or is completely used up, the valve automatically closes, cutting off the water supply—thus achieving the goal of "buying water first, then using it." This meter can also record its operational status and, via a microcomputer running system management software, display the meter’s operating conditions. Moreover, the company provides comprehensive after-sales service.

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.”
