The measurement of air and gases in chemical plants is essential in many functional applications, including safety, process control, product quality, production efficiency, environmental compliance, and cost. When the measurement of air or gases is inaccurate or inconsistent, the result can be serious accidents, emergency shutdowns, unplanned maintenance, production slowdowns, or cost overruns.

Oil and gas companies rely on accurate flow measurement anywhere that hydrocarbons are being stored — including terminals and loading/offloading facilities — as well as upstream, where crude oil is pulled from the ground and small amounts of gas byproduct are commonly flared.

The purpose of this paper is to discuss how to decrease alarms due to redundant level devices not matching, especially in applications with high pressure and/or high temperature. Understanding the importance of gas phase compensation (GPC) and how it affects level readings of guided wave radar (GWR) devices is critical. The presence of polar gas also can affect the accuracy of any GWR that does not have GPC when installed in applications where high temperature or pressure is present. This paper will discuss these issues and address how to overcome them.
