SAW flowmeter with explosion protection approval
This company’s FLOWave flowmeters (photo) are now approved for use in potentially explosive atmospheres. Hygienic measurement without media contacting sensor elements in the tube is thus also possible in Ex zones with flammable solvents, such as alcohols, for the production of pharmaceutical products, spirits, semiconductors and paints. For a reliable process, quality and production guidelines must be observed and production parameters documented, even with frequent product changes. The FLOWave flowmeter Type 8098 is offered as an ATEX-certified version up to Ex zone 2 for production processes in potentially explosive atmospheres. The flowmeter operates according to the surface acoustic wave (SAW) method. With this measuring principle, there are no dead legs or sensor elements in the measuring tube. The clean- and steam-in-place-capable flowmeters can thus be cleaned just as easily as normal pipelines. — Bürkert Fluid Control Systems, Huntersville, N.C.
