The invention relates to a method for correcting a transit-time difference of a useful sound signal from an ultrasonic clamp-on flowmeter, comprising: - providing an ultrasonic clamp-on flowmeter (1) with a first ultrasonic transducer (10), a second ultrasonic transducer (20), and a computing unit (30) connected to the first ultrasonic transducer (10) and the second ultrasonic transducer (20), as well as a medium-carrying pipe (2) with a pipe axis (X), an outer surface (3), an inner surface (4), and a pipe wall (5), - attaching the first ultrasonic transducer (10) and the second ultrasonic transducer (20) to the outer surface (3) at a distance (A) from each other along the pipe axis (X) such thatthat a first ultrasound path (UP1) with at least one reflection at the inner surface (4) and a second ultrasound path (UP2) in the pipe wall (5) can be formed between the first ultrasound transducer (10) and the second ultrasound transducer (20), - Emitting a first ultrasound pulse (UI1) from the first ultrasound transducer (10) to the second ultrasound transducer (20).

Examples provide a future inventory (FI) ordering system that enables orders of temporarily out-of-stock (OOS) items that are not currently on-hand at a fulfillment center (FC). A temporarily unavailable OOS item is made available for purchase with an extended estimated date of delivery (EEDD) as a future delivery (FD) item. A status indicator can be provided to distinguish FD items from currently in-stock items via a user interface (UI) device. Machine learning models are used to predict transit time, dwell time, and / or receiving time for the FD item using lane-specific data, dynamic extrinsic data, and other item-related data. The EEDD is predicted using the predicted transit time. A delivery notification including the EEDD for the FD item to the user via the UI device. Unloading of trailers containing FD items is prioritized at the FC to ensure timely delivery of FD items within the predicted EEDD.
