The Flexim FLUXUS G831 ST-LT measures steam flow non-intrusively from the outside of the pipe in hazardous areas (ATEX/IECEx Zone 1 and FM Class I Division 1 approved). It is highly sensitive even at very low flow velocities and functions independently of the flow direction. Due to this large flow range (flow velocities from 0.01 to 60 m/s / 0.03 to 197 ft/s), there is no need to reduce the pipe diameter to fit an inline meter's requirement of minimum flow velocity. Moreover, the non-intrusive measurement does not cause any pressure loss, and the transducer mountings can be completely insulated to reduce any heat loss to the environment. With FLUXUS G831 ST-LT it is possible to capture all steam usage from very low to very high flow rates with one meter size.
