The Flexim FLUXUS ST measures steam flow non-intrusively from the outside of the pipe, the portable acoustic measuring method proves to be impressive with its exceptionally high measuring dynamics, high sensitivity at very low flow velocities and independence to flow direction. Due to this large flow range (flow velocities up to 200ft/s), there is no need to reduce pipe diameter to fit an inline meter’s requirement of minimum flow velocity. Moreover, the non-intrusive measurement does not cause any pressure loss. The transducer mounts can be completely insulated to reduce any heat loss to the environment. FLUXUS ST has no moving parts. Therefore, FLUXUS ST is not subject to wear and tear and does not require any maintenance.
