In the field of industrial gas flow measurement, traditional instruments often suffer from inaccurate measurement, frequent maintenance requirements, and shortened service life due to dust, liquid droplets in the medium, pressure fluctuations, or variations in pipeline materials. The GF721 Clamp-on Gas Ultrasonic Flowmeter, developed by Shandong Gurui Da Automation Technology Co., Ltd., is emerging as the preferred solution for measuring the flow of various gases—including natural gas, compressed air, biogas, and oxygen—thanks to its core advantages such as non-contact measurement, strong anti-interference capability, and automatic adaptation to medium changes.
Why Choose a Clamp-on Gas Ultrasonic Flowmeter?
The greatest advantages of clamp-on gas ultrasonic flowmeters lie in their easy installation, non-contact with the medium, no pressure loss, and maintenance-free operation. They are particularly suitable for gas measurement scenarios involving corrosive media, high temperature and pressure conditions, or strict hygiene requirements. However, traditional clamp-on instruments have long faced two major technical challenges in gas measurement:
1. Weak sound wave penetration: Gases have low sound velocity, while metal pipe walls have high sound velocity, leading to significant sound wave attenuation at the interface.
2. Pipe wall noise interference: Part of the sound wave propagates along the pipe wall, generating noise that disrupts signal reception.
Gurui Da has completely addressed these pain points through multiple core technological breakthroughs. The Gurui Da GF721 Clamp-on Gas Ultrasonic Flowmeter adopts a clamp-on installation method, which eliminates the need for pipe cutting or hot work. This greatly reduces construction difficulty and safety risks. The design not only shortens the installation cycle but also avoids downtime losses, saving users substantial costs and time. Compared with traditional insertion or vortex flowmeters, the clamp-on design is more suitable for measuring high-risk media such as natural gas, hydrogen, and compressed air, truly achieving "ready-to-use, safe and reliable" performance.
Core Technical Advantages of the Gurui Da GF721
1. Wide-beam Sensor Technology for Enhanced Signal Penetration
The Gurui Da GF721 features an innovative wide-beam sensor design that uses pipe wall resonance as the sound wave emission source. This significantly reduces sound wave attenuation at the pipe wall-gas interface. Even when the gas contains 10% (v/v) dust or liquid droplets, the sensor maintains stable signals, enabling reliable measurement of low-pressure gases.
2. Intelligent Sound Velocity Tracking for Adaptive Medium Changes
The flowmeter is equipped with an automatic sound velocity tracking function. It can real-time adapt to sound velocity fluctuations caused by changes in gas temperature or composition, ensuring consistent measurement accuracy without manual intervention.
3. Pipe Wall Noise Reduction Technology for Improved Signal-to-Noise Ratio
Using specialized noise-canceling materials and algorithms, the Gurui Da GF721 effectively suppresses pipe wall-borne noise, resulting in clear and reliable signals. It maintains high-precision measurement even in industrial environments with significant vibration.
4. Solid Coupling Pad Design for Truly Maintenance-Free Operation
The sensor features an all-stainless steel housing and a solid coupling pad, eliminating the need for regular replacement of coupling agents. With an protection rating of IP65/IP68, it is suitable for harsh environments such as high humidity and heavy dust, ensuring long-term stable operation.
