Which of the following pulse damper takes up some amount of the pulsation energy which is released to provide smooth pressure without pulsations?

(a) Flexible bellows or compressible gas passed through tee columns

(b) Flexible inert diaphragm

(c) Electronic pulse damper

(d) Electrical pulse damper

Answer 1

Correct choice is (a) Flexible bellows or compressible gas passed through tee columns

To explain I would say: Flexible bellows or compressible gas passed through tee columns take up some of the pulsation energy which is released to provide smooth pressure without pulsations. Its main purpose is to avoid pulses.
