Flow measurement instrumentation for emissions & analytical solutions - Monitoring and Testing

Sierra manufacturers the BG3 Elite Partial Flow Dilution system for use in diesel particulate sampling.  BG3 Elite is a direct replacement to cumbersome full flow CVS systems in both heavy and light duty emissions applications.  The BG3 Elite can feed properly conditioned diluted sample flow to a Bag Mini-Diluter for gaseous analysis or even to a Particle Number measurement device.
