Abstract
A flow metering apparatus for a passage in a turbomachine component, the turbomachine component, and a method of using the apparatus, are provided. The apparatus may include a pre-sintered preform (PSP) sealing device with a sealing body. The sealing body has an opening defined therethrough having a first cross-sectional area. A hollow member is fixed within the opening defined through the sealing body. The hollow member has a second cross-sectional area smaller than the first cross-sectional area of the opening, and is made of a material having a melt temperature higher than a melt temperature of the PSP material. The method includes positioning the sealing device and brazing the sealing device in place. The hollow member maintains fluid communication through the sealing device after the brazing, and allows customized metering of the coolant flow therethrough.
