This technical report provides documentation of performance characteristics of full-bore liquid vortex meters for measuring liquid hydrocarbon flows of different API gravity under the field operating conditions and under a controlled environment in a laboratory test facility with water as the proving fluid, limited laboratory proving facility test results using water as the calibration fluid of several and 2-in. (50 mm) and 4-in. (100 mm) commercially available full-bore vortex meters that are typically installed for non-custody transfer liquid installations, and typical performance of full-bore 4-in. (100-mm) liquid vortex meters for liquid hydrocarbon measurement and to provide guidance in selecting liquid vortex meters for custody transfer measurement.
