Flexim FLUXUS G831 ST-HT High-temperature Steam Measurement for Hazardous Areas

The Flexim FLUXUS G831 ST-HT non-intrusive steam flow meter measures volume and mass flow of saturated and superheated steam at temperatures up to 630 °C (1166 °F) in hazardous areas.

The Flexim FLUXUS G831 ST-HT measures steam flow non-intrusively from the outside of the pipe. The acoustic measuring method has exceptionally high measuring dynamics and functions independently of the flow direction, offering precise bi-directional flow measurement over a wide turndown ratio up to 10:1 and with no moving parts. Ultrasonic transducers are fixed to the pipe with broad stainless-steel straps or our patented high-temperature mounting system WaveInjector® and secured in robust stainless-steel housings. Intrinsically safe process inputs for pressure and temperature at the meter location means the FLUXUS G831 ST-LT measures volume and mass flow of saturated and superheated steam at temperatures up to 630 °C (1166 °F) in hazardous areas.
