PIPELINE SAMPLE SYSTEM
The APLI automated sampling system is a PC based system with a remote PLC control system. A windows based design simplifies the operator interface and reduces the time for operators to become proficient with the system. Point and click, pull down menus, and tab driven functions make choices easy and readily available for the operator.
The system has been designed to integrate scheduling information, interface considerations, net barrel counts, end of batch indications, and customer specific parameters into a completely automated user-friendly sampling solution.
The APLI automated sampling system has been designed to accurately and reliably cre-ate composite samples from a pipeline batch stream. Remote access and on-site intelli-gence allow for reliable unattended opera-tion. Retained sample representation is great-ly improved, due to multiple small samples taken per batch. Samples are retained on the rack in seamless aluminum cans. Samples are held under pressure to minimize vapor loss.
Scheduling information is entered through a Windows based spread sheet interface that allows for easy editing of schedule parameters. New schedule data can be entered directly into a spread sheet. Batches can be inserted, delet-ed or modified with a minimum of effort and operator training.
The composite sample is very accurately obtained from the user specified parameters and schedule. The system automatically compensates for variations in the piping to the field unit and in the system line fill to a particular can. Several batches can be sampled before operator intervention is required. A virtually unlimited number of batches can be scheduled. Automatic printing of labels for cans and event logging.
