The new measuring system has been specifically designed to record precisely volume and mass flow rates of saturated and superheated steam at temperatures up to 400 °C.
FLUXUS ST-HT measures steam flow non-invasively from the outside of the pipe. Non-invasive steam flow measurement means measuring without any interruption of operation or supply. Since clamp-on ultrasonic transducers are simply mounted on the outside of the pipe, it requires just minimal installation effort and no pipeline penetrations. The acoustic measuring method has exceptionally high measuring dynamics and functions independently of the flow direction. The FLUXUS ST-HT offers precise bidirectional flow measurement over a wide turndown ratio up to 25:1.
The new FLUXUS ST-HT is complementary to FLEXIM’s existing steam flow meter FLUXUS ST, which has been brought to market also as a world first last year and whose application range is limited to temperatures up to 180 °C. Now, the new FLUXUS ST-HT can be applied for steam measurements up to 400 °C in pipes up to 900 mm in diameter. This important extension of the application range has been achieved by the combination of FLEXIM’s patented WaveInjector technology with the cross correlation measuring method.
“Nowadays, it has become quite hard to explore unknown territories”, says Denis Funk, Industry Manager Power at FLEXIM: “We didn’t want to leave this field entirely to Elon Musk. No one before us has succeeded to measure high-temperature steam non-invasively. This accomplishment makes us proud.”
