Valve-Controlled Meter Trivia
The valve-controlled base meter is primarily used in conjunction with the intelligent valve-controlled water meter, which consists mainly of the valve-controlled base meter and a control box.
The valve-controlled base meters are categorized into wet-type, dry-type, and semi-liquid-sealed types. There are two methods for transmitting information: reed switches and Hall sensors. Installation options include both horizontal and vertical mounting. The valve limit switches employ a dual approach, combining switch-based limits with mechanical limits.
A dual-reed switch or Hall-signal sampling method is employed. When the signal pointer rotates once, the two reed switches are attracted once each, constituting one pulse. The two reed switches are attracted at different times. This sampling method effectively avoids the phenomenon of multiple pulses being recorded due to reed switch jitter, ensuring that the mechanical counting and the electronic counting remain consistent. Additionally, this approach enables the system to detect external magnetic field interference: if an external magnetic field interferes, both reed switches will be attracted simultaneously.

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.”
