Now also available for hazardous areas: Non-invasive steam flow measurement


With FLUXUS ST, FLEXIM presented the world’s only clamp-on ultrasonic flowmeter for steam. Now, FLEXIM’s steam flow meters are also available for use in potentially explosive atmospheres. Both stationary and portable transmitters are ATEX-/IECEx-certified for use in zone 2 hazardous areas, according transducers can even be operated in zone 1.

FLEXIM offers two complementary non-invasive measuring solutions for low-temperature as well as for high-temperature steam flow measurement. The FLUXUS ST series allows for volume and mass flow measurement of saturated and superheated steam at temperatures up to 180 °C. FLUXUS ST works according to the well-known ultrasonic transit-time difference principle. Due to its extraordinairy measurement dynamics and its high sensitivity even to low flows, FLUXUS ST does not require opening of the pipe or inserted instruments, and works without a need to reduce pipe diameters in order to achieve a minimum flow velocity. In conjunction with FLEXIM’s patented high-temperature transducer mounting device WaveInjector and the use of the correlation flow measuring technology, FLUXUS ST HT extends the application range of non-invasive steam flow measurement up to 400 °C. With the new and hazardous area certified portable FLUXUS G608 ST, FLEXIM offers a veritable multi-tool: in addition to steam, the measuring system can also measure liquids, gases, compressed air and thermal energy.
