  • Description

    Orifice Meter Runs are complete flow measurement devices, ready for installation, that include a manufacturer installed Orifice Union and Orifice Plate and the required up & down stream pipe sections. Stated uncertainties are contingent upon all code prescribed tolerances and finishes being met. The selection of a complete meter run ensures full conformance to all code specified geometric tolerances and finishes. In cases of smaller line sizes, the pipe sections may require honing in order to be compliant with the applicable code required finish. A fully fabricated run, complete with any variation of NDE required, is the only way to ensure this compliance.
