DRA Injector |
DRAInjector |
The actual pump device that injects DRA into the pipeline as product is flowing by. An injector must belong to a DRA Injector Group to be included in DRA Injection Setpoint Management. |
|
DRA Injector Group |
DRAInjectorGroup |
A grouping of DRA Injectors that indicates that the devices are co-located (that is, injecting into the same location on the pipeline). This grouping will ensure that only a single injector at that location is pumping at any given time. More specifically, it will verify that for a combination of inputs (DRA Product Group, DRA Flow Rate Range) only one injector in the group has a non-zero setpoint. |
|
DRA Line |
DRALine |
The DRA Line is an abstract to a single whole or part of an actual pipeline. DRA Injection Setpoint Management is performed holistically from the viewpoint of the DRA Line. |
|
Product Type |
prodtype |
The system-wide set of pipeline products that are being managed by the AVEVA Pipeline Operations for Liquids installation. |
