    TESTING Rosemount Boulder, Colorado Flow Laboratory LABORATORIES The Rosemount 405 and 1595 is tested and calibrated in water at Rosemount Inc. Line sizes available for testing range from to 12-in. (12.7 to 304.8 mm). A secondary set of reference meters, routinely calibrated against a gravimetric primary standard, provide an uncertainty of 0.25 percent.

  • Page 14: Gravimetric Procedure

    Reference Manual 00821-0100-4810, Rev AA 405 and 1595 March 2004 GRAVIMETRIC Piping is selected to match the inside diameter of the flowmeter under test. Carbon steel piping is normally used for these tests. Gaskets between pipe PROCEDURE flanges are carefully installed and checked to ensure that they not interfere with the flow.
