A device for conveying measured amounts of material which includes a rotating induction wheel having a plurality of elongate open-ended chambers defined therein and a pair of wipers arranged to remove excess material from the chamber ends. Pressure pads seal the chambers, and gas is introduced into the chambers to pulse the material out of the chambers into a material transport conduit. Metered charges of material are thus delivered to the transport conduit.
