Abstract: The present disclosure relates to an arrangement for providing information about a flow rate of a fluid, comprising: a fluid inlet opening, at least one flow channel, and at least one porous zone located above the at least one flow channel, wherein the surface size and position of the at least one porous zone relative to the fluid inlet opening defines the evaporation rate of a fluid, arranged such that when a fluid is injected through the fluid inlet opening the fluid flows via hydraulic pressure through the at least one flow channel and then through the respective at least one porous zone.

Abstract: A pallet can be detachably carried on a sled for shipping heavier objects on the pallet as carried by the sled, or lighter object on the pallet alone, the sled spreading the weight over a greater area than the pallet alone. The dimensions of both the pallet and sled are related to contribute different integer fractions of a given dimension such as the length of a standard intermodal container. This arrangement is apt for shipping smaller steel coils on pallets and larger steel coils on pallets carried by sleds. Thus, for example, quarter-container-length pallets, normally appropriate for a pallet to carry lighter coils, can carry heavier loads on a sled occupying a larger proportion of the container length, such as a half-container-length sled. An attachment mechanism affixes the sled to the pallet and the assembly is configured for manipulation with a fork lift.
