About this Course

Liquid level measurement is critical to the safe operation of a facility.  

The level measurements obtained are used to monitor and control many of the processes in an industrial facility. Numerous technologies exist that measure the liquid level in a vessel; each type uses different principles of physics to sense the level and provide output to a transmitter or transducer.  

The basic types of measurement devices can be broken up into two categories, direct measurement and inferred measurement.
