Patent attributes
A delivery system includes a transportation container for cooking oil carried by a delivery vehicle for filling a storage container located at a restaurant. A flexible conduit is temporarily connected between the transportation container and the storage container. The oil is pumped from the transportation container to the storage container. A pressure sensor, carried by the vehicle downstream the pump, monitors pressure in the storage container. A processor operates with the pressure sensor for determining a pressure level in the storage container and controls delivery of the oil for limiting a pressure level to a preselected value. The system waits a period of time and tests the pressure to allow the pressure in the storage container to equalize so that pressure in the conduit at the vehicle is the same as pressure in the storage container. The pressure level is used to establish the amount of cooking oil delivered.
