Measure flow of high-temperature steam
Fluxus ST-HT (photo) is said to be the world’s first and only clamp-on ultrasonic flowmeter for high-temperature steam. The new measuring system has been designed to precisely record volume and mass flowrates 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 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 this company’s existing steam flowmeter 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 the company’s patented WaveInjector technology with the cross-correlation measuring method. — Flexim GmbH, Berlin, Germany
