In many industrial processes, gas is not used just once but is recirculated – this is referred to as recirculation gas. This is done for various reasons: to save energy, to reduce emissions or to optimize chemical reactions. Recirculation gas can be at high temperatures, contain aggressive components and often be heavily contaminated with particles.
Precise flow measurement is essential to control the process, ensure efficiency and monitor plant performance. However, this measurement is challenging: the space available is often limited, inlet and outlet sections are restricted, and fans are often located in the immediate vicinity of the measuring points. This requires robust measurement technology that works reliably even under difficult conditions.
Our solution: differential pressure measurement with pitot tubes
This application presents particular challenges, including limited inlet and outlet sections as well as heavily contaminated gases. Our differential pressure measurement is based on averaging pitot tubes, which we calculate and dimension individually for each application. In special cases, we use pneumatically coupled crossover measurements to accurately capture the entire flow profile – a measurement method that no other technology offers in this form.
From the selection of suitable materials to purging solutions for heavily contaminated gases, we adapt our measurement technology precisely to the specific process requirements. Our probes can be purged either manually or automatically to ensure consistently reliable operation. Rugged and reliable – even in extreme conditions
Thanks to the versatility of the materials used, our probes are ideally suited for use in aggressive media and at high temperatures. We also offer the option of remote installation of the transmitter, so that even hard-to-reach places can be easily accessed.
Conclusion: long-term solutions for demanding applications
With our solutions, we not only meet the specific requirements of your recirculation gas applications, but also ensure the long-term efficiency and reliability of your processes. We develop customized systems that are optimized for long-term use – so you can focus on what's important.
