What is a U syphon and what is it used for?
A. A coiled tube used to protect the gauge from damage due to overpressure
B. A device used to regulate the flow of fluid to the gauge
C. A device used to reduce the effects of temperature changes on the gauge reading
D. A tube used to protect the gauge from contamination by foreign substances
Answer:A

Explanation: A U syphon is a coiled tube that is installed between the process being measured and the gauge, which protects the gauge from damage due to overpressure. The coiled design allows for expansion and contraction of the fluid, which prevents damage to the gauge due to pressure spikes.
