A mass flow device for a wood chipping harvesting machine and an accelerator assembly for an outlet passage of a mobile wood chipping harvesting machine with a flexible wall portion adjacent the accelerator adjustably controlled by a control mechanism to control the flow of the chips past the accelerator. The outlet passage is operably connected to a chipping device and arranged to allow chips to pass therethrough. A curved wall portion in, or of, the outlet passage is operable to be impacted by the chips passing through the outlet passage. A sensor means operably connected to the curved wall portion measures strain and/or other parameters of the curved wall portion as an indication of mass flow rate of the chips through the outlet passage. |
