摘要： Method for calibrating a device for measuring back pressure in open-ended chemical reactor tubes, comprising the steps of: providing a device for measuring back pressure in open-ended chemical reactor tubes, including a frame member and a plurality of injector tubes mounted on the frame member with a spacing between the injector tubes; providing a test stand, comprising a frame member; a base supporting said frame member; and a plurality of calibration tubes mounted on the frame member, each of said calibration tubes having an open top and a dosed bottom, with a precision orifice in the dosed bottom to simulate the chemical reactor tubes to be tested; inserting the plurality of injector tubes into the respective calibration tubes; sealing between the injector tubes and the calibration tubes; sending gas through the injector tubes and taking a back pressure reading for each of the injector tubes; and generating correction factors for each injector tube to correct for variations in the back pressure readings.
