LXCR Series Large-Diameter Ultrasonic Heat Meter

The Huazigangchuang LXCR series large-diameter ultrasonic heat meter is an instrument used to measure and calculate heat consumption. Its working principle is based on the characteristic that the propagation speed of ultrasonic waves in fluids changes with the change of fluid temperature. By transmitting and receiving ultrasonic signals and measuring the difference in their propagation time and speed, the fluid flow rate passing through the heat meter can be accurately calculated. At the same time, combined with the measured inlet and return water temperatures, the heat consumption can be accurately calculated according to thermodynamic formulas. It features high measurement accuracy, providing accurate and reliable heat data; no mechanical moving parts, thus ensuring good stability, long service life, and low maintenance cost; and low pressure loss, minimizing the impact on the system.

Product Details

Application Scenarios

1. Urban Central Heating System

- Used to measure the heating heat of the entire urban area or large community, helping heating companies to reasonably allocate energy, optimize heating schemes, and achieve accurate billing.

2. Large Commercial Complexes

- Such as shopping malls and office building clusters, due to their large building area and diverse heating needs, large-diameter ultrasonic heat meters can accurately measure the heat consumption of different areas, facilitating energy consumption management and cost accounting.

3. Industrial Parks

- Provide data support for heating metering of various industrial enterprises, helping enterprises understand energy usage, adopt energy-saving measures, and reduce production costs.

4. Hospitals and Schools
- These places have large buildings, dense populations, and relatively stable and large heating needs. Large-diameter heat meters can accurately measure heat, ensuring a comfortable indoor environment, and facilitating energy consumption monitoring by the logistics management department.
