PfFLO III 10704 Air Monitor Corporation

Each PfFLO III coal flow transmitter determines the mass flow rate and particle velocity of pulverized coal, independent of a central processor and/or external inputs such as mill feeder rate. The onboard microprocessor manages the transmitter functionality and performs all data processing, providing reliability with realtime performance.

Basics of Gravimetric and Volumetric Feeding : Plastics

Feed Rate Basics. In the continuous formulation of plastics the primary purpose of feed rate control is to achieve consistently accurate proportioning of recipe components (resin and required additives) prior to pelletization (in compounding) or endproduct forming operations.Feeders produce a precise and controllable discharge rate for the material they are designed to handle.
