  • Powder feed control system and method
    Patent number: 10401246
    Abstract: Powder feed rate control system that includes a hopper adapted to contain a powder and to maintain a hopper pressure. A carrier conduit delivers a carrier gas flow and having an orifice. The carrier gas flow conveys powder entering through the orifice at a powder feed rate. A differential pressure transducer includes a first pressure input associated with the hopper pressure and a second pressure input associated with the carrier gas flow downstream of the hopper. The differential pressure transducer (PT) outputs a signal related to a differential pressure between the first pressure input and the second pressure input. An electro pneumatic regulator (EP) is adapted to communicate with a control and receiving the signal related to the differential pressure.
