The Fluid Allocator is a device added by Thermal Expansion 5. It can be used as a small buffer to store fluids, having 3 different internal tanks, each with the capacity of 8000 mB, to store up to 3 different fluids. Once a fluid enter a tank the tank can be locked to only accept that fluid. Fluid transfer rate, redstone control and input/output side of the block can be configured inside its GUI.
