Product Features
Zero Pressure Loss & No Mechanical Wear
The FH-507 ultrasonic meters natural gas adopts non-contact external measurement structure with no internal movable components. It causes no pipeline pressure drop during natural gas measurement, avoids gas energy loss, and eliminates mechanical wear, greatly extending the service life and reducing daily maintenance frequency for HVAC and heating systems.
High Precision & Wide Turndown Ratio
Equipped with high-sensitivity dedicated gas ultrasonic probes and intelligent signal processing algorithms, the meter achieves measurement accuracy up to ±0.8%. It stably captures low-flow and fluctuating natural gas flow in heating and air conditioning pipelines, with a wide turndown ratio to adapt to variable gas consumption in different seasonal and operational scenarios.
Strong Environmental Adaptability for HVAC Scenarios
Designed for long-term operation in indoor and outdoor heating, ventilation and air conditioning environments, it resists temperature changes, slight dust and conventional electromagnetic interference. It maintains consistent measurement stability in boiler gas supply, central air-conditioning energy-saving monitoring and community heating gas pipeline systems.
Intelligent Data Monitoring & Easy Management
Supports real-time display of natural gas instantaneous flow, total cumulative flow, gas velocity and operating status. It comes with automatic data logging and data export functions, facilitating energy consumption statistics, HVAC system energy efficiency analysis and daily gas consumption management for enterprises.
Working Principle
The FH-507 ultrasonic meters natural gas operates based on the gas ultrasonic transit-time difference principle, complying with international AGA #9 and GB/T18604 industry standards. A pair of ultrasonic transducers are installed on the outer wall of the natural gas pipeline, alternately transmitting and receiving ultrasonic signals that penetrate the gas medium. When natural gas is static, the upstream and downstream signal propagation time is equal. When gas flows, the ultrasonic signal traveling with the gas flow has a shorter transit time, while the counter-flow signal takes longer. The built-in high-speed microprocessor accurately calculates gas flow velocity and instantaneous flow by capturing the precise time difference, and accumulates total gas consumption. Combined with temperature and pressure compensation algorithms, it realizes accurate and stable natural gas flow measurement for HVAC and heating systems.

Installation Method
This ultrasonic natural gas flow meter adopts a convenient external clamp-on non-intrusive installation, requiring no pipeline cutting, drilling or system shutdown, which will not affect the normal operation of HVAC and heating systems. First, select a straight and intact pipe section (avoid elbows, tees, valves and deformed pipe sections) that meets the front and rear straight pipe distance requirements, and clean the pipeline surface thoroughly to remove dust, rust and paint. Then install and fix the two matched ultrasonic sensors on the pipe outer wall according to the standard spacing, and apply special high-temperature coupling agent to ensure tight fitting and stable signal transmission. Finally, power on the host, set parameters such as pipe diameter, pipe material and gas medium, and the meter can complete debugging and start real-time measurement within 5 minutes. The whole process is simple, efficient and free of professional construction.
