Abstract:
1. A device for monitoring the mass flow of a particulate solids flow in a pneumatic pipeline, comprising: a measuring chamber; an impact body within said measuring chamber; and an inlet connection designed so as to blow said particulate solids flow as a compact solid/gas jet onto said impact body within said measuring chamber, so that said compact solid/gas jet impacts onto said impact body with substantially its whole cross-section, said inlet connection having a central axis; wherein said impact body is a stemlike body penetrating into said measuring chamber in axial prolongation of said central axis of said inlet connection, so that said compact solid/gas jet impacts onto a frontal impact surface of said impact body with substantially its whole cross-section; and an acoustic transducer associated with said impact body outside of said measuring chamber for sensing structure-born acoustic waves generated by said compact solid/gas jet impacting onto said impact body, and for converting them in an output signal for monitoring the mass flow of a particulate solids in a pneumatic pipeline.
