FLUXUS G831 ST-HT
FLUXUS G831 ST-HT
The FLUXUS G831 ST-HT is our smart solution for high-temperature steam flow measurement in hazardous areas.
Non-invasive and efficient
FLUXUS G831 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.
This unique flow solution is based on the correlation flow measurement principle. The acoustic measuring method has exceptionally high measuring dynamics and functions independently of the flow direction. The FLUXUS G831 ST-HT offers precise bidirectional flow measurement over a wide turndown ratio up to 25:1.
Completely maintenance-free, robust and safe in operation
Non-invasive steam flow measurement also means measuring without direct contact with the medium flowing in the pipe. FLUXUS G831 ST-HT has no moving parts. Its 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.
Therefore, FLUXUS ST-HT is not subjected to wear and tear and does not require any maintenance. No more venting and draining of inline flow equipment is necessary, which ensures a totally safe operation of our flow measurement solution.
The addition of 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 400 °C in hazardous areas.
