Upgrading of Waukesha CFR octane test engines for fully automated on-line operation is now available that fully and in all details conform to ASTM D2885 test method. Unlike other systems, there is NO modification to the CFR engine, and on-the-fly switching from automated to manual operation is done by a simple turn of the fuel selector valve and a single electrical switch.
Depending on the degree of automation selected, data is captured from the knock meter, cylinder height position, and detonation meter. The software does all data management, calculations, and data storage. This data capture offers full, simplified ISO traceability with full documentation. Detailed reports are printed out at end of each test or on command. Historic data is easily retrievable. This data is available for transfer to a LIMMS for storage or to a spread sheet for further analysis.
Depending the degree of automation selected, the cylinder height position, and detonation meter parameters are automatically adjusted.
Detailed reports are printed out. Historic data is easily retrievable from the hard drive. This data is available for transfer to a LIMMS for storage or to a spread sheet for further analysis.
All ASTM method tables are automatically corrected for barometric pressure with internal sensors.

consists of a cabinet with a PC, printer and assorted electronics. Windows based proprietary software manages the engine operation and the capture and management of knock meter data. The knock meter drift is automatically compensated.

ROFA Model 2885-SC
|
the same as ROFA Model 2885-S above but with the additional capability of automated adjustment of cylinder height and the capture of the cylinder height position
|
|
ROFA Model 2885-SCD
|
the same as ROFA Model 2885-SC above but with the additional capability of automated parameter control of the detonation meter and the capture of the detonation meter data.

ROFA Model 2885-SCD
|
offers octane number precision improvement. The limit of confidence for octane number is ±0.16 O.N. Limit of tolerance for 15 successive tests is 0.26 O.N. This improved precision allows the refinery to operate with a significantly lower give away, up to 70%. The cost if this automation can be recovered in a few months.
