An example shunt tube assembly includes at least one shunt tube that defines an inner flow path for a fluid and provides an upper portion and a lower portion. At least one shunt fitting is positioned inline between the upper and lower portions of the at least one shunt tube. The shunt fitting provides an outlet that fluidly communicates with the inner flow path to provide an exit for at least a portion of the fluid to be discharged from the at least one shunt tube.
