How can an instrumentation engineer prevent foam from affecting level measurement readings in a tank or vessel?
A. Use a specialized foam-resistant level transmitter
B. Install an air purging system to remove foam from the tank or vessel
C. Adjust the level transmitter’s sensitivity to account for the foam
D. All of the above
Answer:D

Explanation: Foam can affect level measurement readings by causing the level transmitter to incorrectly detect a higher level than is actually present in the tank or vessel. To prevent this, an instrumentation engineer can use a specialized foam-resistant level transmitter, install an air purging system to remove foam from the tank or vessel and adjust the level transmitter’s sensitivity to account for foam.
