Saab is one of the world’s largest producers of level gauges and has sold and installed more than 30,000 gauges worldwide. Saab requires that all installations of the above- captioned device be performed by Saab’s personnel, who are the sole source of maintenance for the gauges. Additionally, Saab maintains records on the sale and installation of all such gauges worldwide.
