Question 1 of 27070

All of the following are acceptable means to measure a liquid level in a cyrogenic cargo tank except __________.

🔍 Key Concepts

• Cryogenic cargoes such as LNG and how extremely low temperatures affect equipment and materials • Typical level gauging systems used on gas carriers (mechanical, electronic, pneumatic) • Compatibility of measuring methods and materials with very low temperatures and cargo vapors

💭 Think About

• Which of these systems can work without physically opening the tank and exposing equipment or people to cryogenic vapors? • Think about what materials or techniques might become brittle, unsafe, or unreliable at -160°C and below. • Which options are commonly installed as permanent tank gauging systems on modern gas carriers and which looks more like a crude or older method?

✅ Before You Answer

• Verify which methods are listed in gas carrier or cryogenic tank references as approved level gauging systems. • Check which option would require direct manual contact with the liquid or vapor space and whether that’s acceptable for cryogenic cargoes. • Consider which method could leave residue or contamination inside a tank designed for very clean cryogenic service.
