Turbine flowmeter is a common type of flow meter. Install process connections to ensure that the tube goes upstream and downstream of the meter place. The minimum straight run upstream should be at least 20 diameters and the straight run downstream should be at least 5 diameters length.

Install the meter so that the flow direction arrow on the sensor case matches the actual forward flow of the process. (Flow direction is also software-selectable.) 2.2 Best practices • There are no pipe run requirements for Micro Motion sensors. Straight runs of pipe upstream or downstream are unnecessary.

People familiar with flow measurement know that flowmeters often require a good velocity profile upstream of the flowmeter to measure accurately. Throttling a control valve causes its velocity profile downstream to become distorted. David W. Spitzer is a regular contributor to Flow Control magazine and a principal in Spitzer and Boyes, LLC
