Abstract
Disclosed herein are systems and methods for measuring and controlling a flow rate through a particle counter or active air sampler. As disclosed herein, a fluid flows through a venturi tube and an orifice in the system at a predetermine velocity. A pressure differential between an inlet of the instrument and a throat section of the venturi tube is measured. The flow rate through the system can be determined based on the pressure differential and an intensive property of the fluid. An alarm can be activated when the flow rate is outside of a flow rate range.
