What is a diaphragm seal and what is it used for?
A. A device used to regulate the flow of fluid to the gauge
B. A device used to protect the gauge from damage due to overpressure
C. A device used to isolate the gauge from the process being measured
D. A device used to reduce the effects of corrosive or viscous fluids on the gauge
Answer:D

Explanation: A diaphragm seal is a device that is installed between the process being measured and the gauge, which protects the gauge from corrosive or viscous fluids. The seal consists of a flexible diaphragm that is in contact with the process fluid, and a fluid-filled chamber that transmits the pressure to the gauge. This allows the gauge to be used in applications where the process fluid is aggressive or difficult to measure.
