We have the tools and expertise to measure and certify your orifice carrier and meter run to ensure full compliance with ISO5167. Manufacturers dimensional certificates often only cover the orifice carrier, and measurement tend to be taken prior to welding to the upstream pipework which can change some of the internal dimensions. Our dimensional inspections look at the entire meter run, ensuring that it is fully in compliance with ISO5167, or identifying non-compliances which can then be rectified prior to certification.
