Flexim-FLUXUS G831 ST-HT High-temperature Steam Measurement

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

Product Description

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 bidirectional flow measurement over a wide turndown ratio up to 10:1 and 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 1166 °F in hazardous areas.
