Overview

The integral orifice meter run assembly is a differential pressure flowmeter especially designed for smaller line sizes where the surface roughness, weld seams and other geometrical imperfections have a relatively big influence on the measurement uncertainty. The DP flowmeter therefore features a minimum length of upstream and downstream pipe, reducing additional uncertainties of the installation to a minimum. It is suitable for process and allocation measurement of gases and liquids including viscous fluids, fluids with suspended solids or fluids with gas entrainment. KROHNE offers the complete orifice assembly with orifice meter run, DP transmitter, valves, accessories, engineering, and documentation. The DP flowmeter comes pressure tested and ready for commissioning.
