Exemplary embodiments are directed to venturi bypass systems that generally include a fluid inlet and a fluid outlet. The systems can include a venturi path disposed between the fluid inlet and the fluid outlet. The venturi path can include a venturi defining a venturi inlet and a venturi outlet. The systems can include a bypass loop connected to the venturi path at a joint upstream of the venturi outlet. The systems can include a separation tube connected to the venturi outlet. The separation tube can extend fluid flowing through the venturi path downstream of the joint at which the bypass loop connects to the venturi path. Exemplary embodiments are also directed to methods of regulating fluid flow through a venturi bypass system.
