The basic concept of interface detection is simple: detect and direct the flow of different batches of refined fuels through pipelines. The implementation, however, can be very complicated. Batches of product arrive at pipeline terminals with interface between each batch. The goal of interface detection is to time the switching or cut of the incoming product in such a way that delivers the maximum quantity of product to customers without downgrading the quality of the product... Inaccurate interface detection leads to an increase in both downgraded product (i.e., selling 91 octane as 85) and transmix, (i.e. a mixture of diesel and gasoline) which requires storage and additional refining. Both significantly cut into the profit margins on delivered product... Historically, the most common method of interface detection was the use of densitometers. Most metering stations contain an existing densitometer. Measured shifts in product gravity from metering station densitometers combined..
