Kurz 452-08-12 Mass Flow Sensor This item was purchased from a large business inventory reduction sale. I do not know the history of it. There is a tag attached to it that reads, "P/N 752731-03-23-20-01-88-01-01-0000-11". Many of the items from this purchase turned out to be new or refurbished items that were kept as spares. This unit looks like it may be new or refurbished and then not put back into service. The tube measures about 14 7/8" long by about 1/2" in diameter. I am not able to test it. It only comes with what is shown in the pictures. S551-2 d
