The Powder Flow Pro V1.1 is an updated version of the company’s automated software used to control its Powder Flow Tester. Significant changes include a modified test method designed to achieve “critical consolidation” of the powder sample contained in the shear cell. Updated data graphics and improved test formats are also provided. The software is available via download free of charge to customers who have purchased the tester. With this new critical consolidation procedure, the shear cell trough turns in repeated short rotations while a constant consolidation stress is applied by the vane lid. This causes the powder material to settle into place, removing air pockets and achieving a “low-energy” state. With the powder packed as tight as possible, the instrument can then determine the powder’s failure strength by shearing the material in the lid against the material in the trough. The software also features improved graphing capabilities, allowing for additional ways to use and manipulate data.
