Using a state-of-the-art vision system and software, the Opti-Flow from Triple/S Dynamics Inc. scans the surface profile of a material as it conveys, collecting real-time data on the material’s cross-sectional area and velocity to calculate the volumetric flow rate. Manufacturers can integrate the unit into conveying systems without modifying an existing equipment layout. The Opti-Flow can also be tied to an existing programmable logic controller (PLC) with a 4-20mA signal output or supplied with a standalone volumetric rate monitoring enclosure. Applications include snack foods.
