A fluid meter particle isolating system having a tortuous path formed between a pair of walls with an inlet and an outlet. The inlet is open to a contaminant-free (clean) zone while an outlet is open to a particle generating contaminated (dirty) zone. The walls include partitions that form a tortuous path separating it into a plurality of chambers. An impeller constructed of a plurality of open cells forms a piston-like structure is provided in the tortuous path and has an axis of motion parallel to the walls. Each vessel is offset axially and has four walls and a bottom surface contoured to provide a transition from one cell to the next through an exit port providing a continuous flow from the vessel in the first cell sequentially to adjacent cells to an exit port in the last vessel in the last cell.
