Allison Engineering have extended their range of laser-based instruments with a new 2D volume flow scanner and 3D laser belt scanner. The former provides continuous, non-contact m~3/h volumetric flow measurement of bulk solids tying on belts and conveyors, while simultaneously monitoring the belt speed. The result is a 2D cross-sectional area of bulk material, while the belt speed provides a 4-20mA output, which is scaled in mVmin.
