you can make a surface monitor for mass flow rate through a surface (inlet or outlet) under report definitions. This gives you the flowrate at every timestep - integrate the whole thing in time to get the total. I assume you use pressure inlets or so? For a velocity inlet, you can just get it from velocity * area * time.
