Abstract
A method is shown for installing a product monitoring device in an underground storage tank, such as the tanks used to store petroleum products. A product sensor is passed through the annular space defined between the tank riser pipe and fill pipe into the tank interior. The product sensor is used to sense representative characteristics of the product located within the tank interior.
