Managing Thermal Expansion in Liquid Level Measuring
Patrick McGrathManaging thermal expansion in liquid level measuring is a common issue in refinery and chemical applications that put level gauges outside the vessel or tank. In this configuration, the gauge is exposed to atmospheric conditions that may affect the temperature of the …
Isolation Valve Design: Repair Dual Level Gauges without Downtime
Patrick McGrathBecause even the highest quality instruments eventually fail, process plants typically have redundant measurement devices for mission critical applications such as for process vessels. A dual level gauge, which includes both a magnetic level indicator (MLI) and a …
