In checking the level of a tank, three pneumercator readings have been taken. If each reading is higher than the last, this indicates that __________.

🔍 Key Concepts

• Pneumercator operation – it uses air pressure in a tube to balance the liquid level in a tank • Relationship between air pressure in the tube and liquid level in the tank • What happens if there is a leak or restriction in the tubing or air supply

💭 Think About

• As the readings get higher, what does that say about the air pressure being applied to the tank through the pneumercator system? • If air supply were excessive or insufficient, how would the pattern of readings likely behave over time? • What physical change in the system would cause the gauge to show progressively higher apparent levels even if the actual tank level stayed the same?

✅ Before You Answer

• Identify whether a higher reading on a pneumercator corresponds to more or less air pressure in the system • Consider how a leak in the tubing would affect the pressure in the system and thus the reading trend • Think about whether a sticking relief valve would produce random/erratic readings or a steady increase with each check

Question 1 of 27070

In checking the level of a tank, three pneumercator readings have been taken. If each reading is higher than the last, this indicates that __________.

excessive charging air was supplied

insufficient charging air has been supplied

the relief valve is sticking

the tubing between the tank and the gauge has a leak
