creates FLAT INVERT VENTURI TUBE
The three sections shown here make up a flat Invert Venturi Meter Tube. As may be noted in the photograph, the diameters of the inlet and outlet sections vary, but the bottom remains on a level plane. Tricky? Maybe! Our craftsmen made the inlet and outlet sections by the art of Loam Molding. The center section or throat was made in a dry sand mold. The three castings weighed a total of 17,800 lbs. The laying length of them was 22 feet iy2". We did all machine work and testing to the specification of our customer—B-l-F Industries, Inc.
