A pinch valve includes a spring disposed between a movable iron core of a solenoid and an end cover thereof, and which urges the movable iron core toward the side of a tube provided in a body. An elastic force of the spring is set to be smaller than a reactive force of the tube that is applied to a valve plug. In a non-excited state of the solenoid, the valve plug is pressed toward the solenoid by the reactive force of the tube, so as to enable a fluid to flow through a flow passage of the tube. Conversely, in an excited state of the solenoid, since an attractive force of the movable iron core toward the tube is added to the elastic force of the spring, the valve plug is pressed in opposition to the reactive force of the tube for thereby blocking the flow passage.

Disclosed are methods, systems, and computer program products for determining a volume of liquid product in a manifold set of tanks. The method includes identifying a plurality of book volumes of liquid product in the manifold set of tanks. The method further includes identifying a plurality of measured physical volumes of liquid product in the manifold set of tanks, each measured physical volume being associated with one book volume of the plurality of book volumes. Following collecting the volumes, the method includes determining a variance between each measured physical volume of the plurality of measured volumes and each book volume of the plurality of book volumes and then using those variances to generate an expected variance to each of the plurality of measured physical volumes, the combination of the expected variance and the measured physical volume being the volume of the liquid product in the manifold set of tanks.

Disclosed are methods, systems, and computer program products to prevent a delivery vehicle from making an unauthorized delivery of liquid product to a liquid product storage tank at a retail store facility. A retail system and / or a centralized inventory management system can monitor one or more tanks at the retail facility for liquid product delivery from the carrier. The retail system and / or the centralized inventory management system can automatically interrupt delivery of liquid product when the delivery vehicle begins to delivery the liquid product to an unauthorized tank.

Disclosed are methods, systems, and computer program products for collecting and communicating temperature and volume data directly from a dispenser for use during a book to physical reconciliation process. The temperature and volume readings can be received directly from a dispenser by at least one of a retail system and a central inventory management system. The method can include collecting flow data indicative of a volume of a liquid product dispensed from the dispenser at a plurality of times during a defined time interval and collecting temperature data indicative of a temperature of the liquid product dispensed from the dispenser at the plurality of times during the defined interval. Once collected, the temperature data and the flow data can be transmitted to at least one of a retail system and a central inventory management system.

Disclosed are methods, systems, and computer program products for performing an on-demand book balance to physical balance reconciliation process for liquid product. The method can include receiving an indication that a delivery of product is about to occur at a retail facility. Based on the received indication, and optionally while fuel is dispensed from one or more storage tanks, a first book balance to physical balance reconciliation can be initiated for one or more storage tanks at the retail facility prior to receiving a delivery of liquid product. Following completion of the first book to physical balance reconciliation, an amount of liquid product as indicated on a delivery document is delivered and then the system automatically performs a second book to physical reconciliation process to identify one or more discrepancies between the amount of liquid product in the storage tanks and a physical amount of liquid product actually delivered.
