Magnetostrictive Level Measuring in Mobile Machines
| Trey Himes | LevelWhen it comes to working under harsh conditions, mobile machines in the construction, agriculture, mining, and material handling industries — as well as in the military — are at the top of the list. Measuring instrumentation needed to ensure safe and efficient …
Managing Thermal Expansion in Liquid Level Measuring
| Trey Himes | LevelManaging thermal expansion in liquid level measuring is common in many refinery and chemical applications to put liquid level gauges outside the vessel or tank. In this configuration, the gauge is exposed to atmospheric conditions that may affect the temperature of …
Isolation Valve Design: Repair Dual Level Gauges without Downtime
| Trey Himes | LevelBecause 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 …
Overlooked Instrumentation Can Lead to Safety Incidents
| Tony Maupin | Know-howThe devil truly is in the details. Level indicators and temperature measurement devices are classic examples of the kind of small—but important—instrumentation that people in the oil and gas industry must be ever vigilant about. Instruments must provide …
