ABSTRACT:
Subsonic venturi proportional and isokinetic sampling methods and apparatus for use in evaluating exhaust emissions from an exhaust source which utilizes a pair of calibrated subsonic venturi restrictions for measuring the bulkstream and extracted sample flow rates respectively. The subsonic venturis may be specifically configured relative to each other to provide isokinetic sampling under specified control conditions.
