Abstract:
    Using single circular ring type static sensor, the invention implement measures average velocity of grains, simplifies measuring device, and reducing dependence of flow condition between two phases of gas and solid. Belonging to non-contact type, the static sensor does not influence on flow condition of liquid in structure. Based on spatial filtering method of static sensor, the technique for measuring average velocity of grains possesses features of simple structure, convenience of processing signal, low cost, and high measuring accuracy. The invention is applicable to site environment of inclement industrial pneumatic transport. The invention carries out experimental study systematically on experimental installation of gravity handling grain flow, and compressive dense phase pneumatic transport system. The result indicates that the measuring system possesses good repeatability and stability.
