    Abstract: An additive fabrication apparatus is provided comprising a movable foil guiding stage (180) having a contact face (181) and comprising on opposite sides of the contact face a pair of upper and lower foil guiding elements (190, 191), the lower foil guiding element (190) defining a foil height position (H0) distanced from the contact face (181), for guiding a foil (6) including a liquid layer (30) to or from the contact face to contact a tangible object (50) by movement of the foil guiding stage along the tangible object while keeping the foil stationary relative to the object (50). An energy source (90) is arranged for at least partially solidifying at least part of an intersection pattern in the liquid layer arranged on the foil and in contact with the tangible object.

    Abstract: Fluid flows through a conduit. To measure flow speed the fluid is heated at a heating location in the conduit with a time-dependent heating strength. A speed of sound in fluid flowing in the conduit is measured at a plurality of sensing locations downstream from said heating location. The flow speed of the fluid is determined from a delay with which the time dependence is detected in the sound speeds measured at said sensing locations. In an embodiment a frequency of the variation of heating strength that is used to determine the flow speed is selected automatically dependent on the flow speed and/or other circumstances.
