Page 15: Chapter 4 General Information
4. General Information System Description The GRA Sampler is designed to collect a representative sample of granular, flake, pellet, slurry or other materials in a vertical gravity conveying line. Sample collection is initiated in response to either an operator’s manual command or a signal automatically generated by controller logic, usually time-based but which could also be volume or quantity based. -
