The Flexim FLUXUS G831 ST-LT measures steam flow non-intrusively from the outside of the pipe in hazardous areas. Highly sensitive even at very low flow velocities and functions independently of the flow direction. Due to this large flow range (flow velocities from 0.03 ft/s to 196 ft/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 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.
