ABB Measurement & Analytics Orifice meter run OMR

ABB standard meter runs comprise of an upstream section with 16 diameters of straight pipe and a downstream section with 8 diameters of straight pipe. The Fiscal version of the meter run is manufactured using specially selected pipe and the orifice calculations are based on the actual (not nominal) measured pipe internal diameters. If higher accuracy is required, these assemblies can be flow calibrated.
