Required Pipeline IDs for Flow Measurement Pressure-Temperature Compensation
Jim Cahill
I received a call the other day and wanted to capture the question and answer for other people Googling around with similar questions. The question: What are the required distances in pipeline inside diameters (I.D.) upstream and downstream for a differential pressure (DP) flowmeter for the pressure and temperature sensors doing pressure-temperature (PT) compensation? I turned to my friends on the Rosemount DP Flow…
