Pulsation Reduction By Acoustic Filters For Metering Applications

Author: Ray G. DurkeDownload File

Because of the adverse effects of pulsations on orifice and other types of flow meters, there is a need at many installations to decrease the amplitude of pulsations in the piping. This task has been the primary domain of acoustical piping designers who have had both theoretical and practical field experience in such areas. The most common and effective treatment for pulsation control is the design and installation of acoustic filters. However, poorly designed filters can be ineffective or expensive to operate. This paper discusses the basic principles and considerations in acoustic filter design
