Abstract
An assembly for measuring metal powder material mass flow rate during direct metal deposition. A detection strip is placed in the gas-blown metal powder material flow path. The detection strip is fixed in one end and suspended at the other end. The flowing metal powder material particles induce displacement to the detection strip. A displacement measurement sensor measures the amount of displacement of the detection strip. The amount of displacement of the detection strip gives relationship to the amount of the metal powder material flowing in the metal powder material flow path. The detection strip and the sensor are connected to a housing with a metal powder material inlet port and metal powder material outlet port and includes internal features for smooth travel of metal powder material particles.
