  • Methods and apparatus for monitoring particles flowing in a stack
    Patent number: 8375766
    Abstract: An apparatus (7) for monitoring particles flowing in a stack (6), comprises: an electrical-interaction monitor (1) operable to provide a signal (300) resulting from electrical interaction of the particles with the monitor (1). a scattered-light monitor (10) operable to provide a signal (310) resulting from detection of light scattered from the particles, and a controller (320) arranged to alter the calibration of the electrical-interaction monitor 1 in response to changes in the relative magnitude of the electrical-interaction (signal 300) and the scattered-light signal (310).
    Type: Grant
    Filed: December 19, 2007
    Date of Patent: February 19, 2013
    Assignee: PCME Limited
