Learn something new: What are the different types of heat meters?
A heat meter is an instrument used to measure heat. Thanks to its simple operation and smart, convenient features, it has consistently received positive feedback from users. However, the market offers a wide variety of heat meters. Below, we’ll introduce the different types of heat meters available, helping you better understand them in the future.
The installation structure and principle of heat meters can be categorized into types such as mechanical and electromagnetic.
1. Mechanical heat meter
Mechanical watches are primarily divided into two types: single-stream and multi-stream. In a single-stream watch, water flows in from one direction inside the watch to rotate the rotor. In a multi-stream watch, water flows in from multiple directions inside the watch to rotate the rotor. The warranty period for mechanical watches is generally two years.
2. Ultrasonic heat meter
An ultrasonic heat meter, as its name suggests, is a general term for heat meters that employ ultrasonic flow meters. It calculates the fluid flow rate by measuring the difference between the speed of an ultrasonic wave traveling with the flow and the speed of an ultrasonic wave traveling against the flow.

3. Electromagnetic heat meter
An electromagnetic heat meter is a general term for heat meters that employ electromagnetic flowmeters. Due to the complex sensor structure and intricate manufacturing processes, these meters are expensive and have high power consumption.
The above is a summary of the main classifications of ultrasonic water meters. They can also be categorized based on factors such as structure, function, and power. We hope this information is helpful to you. If you have any further questions, feel free to call us at 0314-532916—we’re always here to assist 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.”
