ABSTRACT:
A particle flow monitor mounted on a housing having a passage for carrying moving fluid and particles produces audio signals that are in proportion to the amount of particles moving with the fluid. The monitor has a sensing unit having one or more enclosed chambers or cells closing an open end of the housing. A portion of the sensing unit is exposed to a flow chamber within the housing. Particles that impinge on the portion of the sensing unit produce an audio signal which provides audio information feedback as to the amount of particles moving with the fluid.
