Problems such as cavitations, flashing, and aerodynamic noises are also discussed, as well as, common solutions to these problems using different control valve trims and materials. Instrumentation topics are expanded from course 1400 to include troubleshooting and advanced calibration for split ranging, non-compatible signals, or using additional instruments such as a volume booster and trip valves.
