Answer :
Final answer:
The best way to protect a pressure gauge from pressure surges is by using a snubber, which dampens rapid changes in pressure. Other options like shutoff valves, disconnecting the gauge, or plug valves do not provide the same level of protection. A snubber specifically addresses the issue of pressure spikes effectively.
Explanation:
Protecting Pressure Gauges from Surges
The best way to protect a pressure gauge from pressure surges is by using a snubber with the gauge. A snubber is a device that reduces the effects of pressure spikes by dampening the rapid changes in fluid pressure that can cause damage to the gauge.
Here is a brief overview of the other options:
- A. Installing a shutoff valve: While this can help control fluid flow and prevent back pressure, it does not specifically protect the gauge from surges.
- B. Disconnecting the gauge: This would prevent any reading and is not a practical solution for operation.
- C. Installing a plug valve: This is primarily used for flow control, not for protecting instruments like pressure gauges.
In summary, to protect pressure gauges effectively, particularly against surges, a snubber is the preferred option because it directly mitigates the impact of sudden pressure changes, extending the gauge's lifespan and ensuring accurate readings.
