Partially Closed Valve Effects On Electromagnetic Flow Meter Accuracy, Jordan Clark Jarrett May 2016

Partially Closed Valve Effects On Electromagnetic Flow Meter Accuracy, Jordan Clark Jarrett

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

As the need to manage water resources increases, the ability to accurately measure use becomes crucial. In industry, measurement inaccuracies can cost either the
supplier or consumer large amounts of money or even result in a depleted resource. Generally, flow meters need a flow profile to be fully developed so to optimize
measurement accuracy.

In order to produce accurate measurements, most flow meters require a straight section of pipe immediately upstream of the meter. The straight pipe helps to develop the flow profile and produces flow conditions that are as ideal as possible. In many field installations, space restrictions lead …


The Effects Of Upstream Straight Pipe Length On Magnetic Flow Meter Accuracy, Bradley C. Clawson May 2016

The Effects Of Upstream Straight Pipe Length On Magnetic Flow Meter Accuracy, Bradley C. Clawson

All Graduate Theses and Dissertations, Spring 1920 to Summer 2023

In closed conduit water systems, being able to accurately measure flow is absolutely essential. For many meter designs, including electromagnetic induction meters (also known as magnetic flow meters), the greatest accuracy is achieved when the device is calibrated correctly. Optimal meter accuracy often depends on the flow conditions associated with the upstream geometry in the pipe system. Manufacturers typically give standards for the length of straight pipe required upstream of the meter. These standards vary, however, and do not address every possible configuration that may be installed upstream of the straight pipe requirement.

An investigation on the effects of the …
