Level is the height of a liquid surface in reference to a starting point or zero. Knowing and maintaining proper levels contributes to safety and environmental compliance. Knowing how much material is located within a vessel is important to make definitive judgements about the process.

The Level Measuring Devices training course looks at instruments used to measure or sense the level of a tank, silo, or other vessel. It identifies various level sensing and measurement devices and describes their operation. This online course focuses on:

• Review of level measuring methods
• Direct measurement instruments
• Indirect measurement instruments

Level Measuring Devices is part of the Process Control Variables training series.
