Example of a Knowledge and Recall Question:
What is the principle of operation of a bullseye level gauge when used on a steam boiler application?
- Conductivity of water.
- Voltage change of a thermocouple.
- Differing refractive indexes of steam and water.
- Resistance change of a resistance temperature detector.
Answer: C
Procedural and Application
This type of question tests your ability to apply your knowledge of procedures to a situation.
