To Whom It May Concern:

Subject: KAM OID Optical Interface Detector

Shell Pipeline Company, LP has installed several KAM OID Optical Interface Detectors on its product pipelines in the past (2) years. To date, the KAM OID has been extremely successful in detecting product interfaces and has been tested with the following interfaces: CONV87/CONV93, CONV93/RFG87, RFG87/RFG93, RFG87/CONV87, CONV87/LSD, LSD/Kerosene, and LSD/HSD. Since installation, the OID has very accurately sensed optical changes that have passed the device.

KAM CONTROLS' personnel have provided unparalleled support for the installation, start-up, training, operation, and testing of their instruments. It goes without saying that this equipment has been a very useful tool in Shell Pipeline's automation strategy, and the KAM Controls' staff have been a pleasure to work with.
