What is an ultrasonic water meter, and what are its features?
An ultrasonic water meter is a new type of water meter that measures the flow rate of water by detecting the time difference caused by changes in the speed of ultrasonic sound beams as they propagate upstream and downstream in the water. This time difference is analyzed and processed to determine the water’s flow velocity, which is then used to calculate the water’s flow rate accurately.

Features of ultrasonic water meters:
(1) Utilizing ultrasonic flow measurement technology, this system features zero pressure loss and no mechanical rotating parts, thereby reducing pump energy consumption and lowering water supply costs.
(2) High reliability—can operate for extended periods at any flow point, and measurements are unaffected by magnetic interference.
(3) Battery-powered; a single battery can operate continuously for over 6 years. Low start-up flow rate with high accuracy.
Chengde Longzhida Intelligent Instruments & Meter Technology Co., Ltd. develops water meters that feature high quality, simple installation, and comprehensive after-sales service. Feel free to call for more information.

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.”
