In any system which employs gages for either absolute or differential pressure determination, pulsations are likely to present a major problem in that their presence makes accurate gage readings impossible. Several commercial dampers are available which do an adequate job of damping for pulsations of high frequency (i. e. ≥̄ 5cps), Pulsations in the range 0–5 cps, however, are extremely difficult to damp out and commercially available dampers frequently will not do an effective job.
