Emerson has launched the Fisher WhisperTube Modal Attenuator for noisy gasoline or vapour functions, which presents noise discount in compressible fluid service for improved employee safety, with no impression on process circulate.

The modal attenuator from Emerson is a full-bore device offering 15-decibel sound suppression to cut back noise inside pipes produced by sources upstream, such as management valves or other gadgets. It is installed downstream of these units rather than a pipe spool piece, it generates no extra pressure drop, and has no impression on process move.
Until now, all solutions have generated important stress drop, reduced flow, and/or introduced obstructions. This has led some users to put in acoustic insulation to pipe sections to cut back noise, however this could be expensive and cumbersome to install, and it does nothing to reduce internal piping noise. เกจวัดco2 addresses these and other issues with a drop-in answer, improving employee safety and regulatory compliance, while decreasing the chance of harm to downstream equipment due to excessive noise levels inside to piping.
Leading purposes for the modal attenuator embrace those where upstream process flows are modified by management valves, pressure relief valves, pumps, compressors and different gadgets that generate noise. Many of these units must be put in in lengths of piping with no move restrictions downstream, and the modal attenuator works properly in these purposes as a result of it introduces no such restrictions.
In addition, the modal attenuator does not introduce an obstruction into the piping, so it could be used in purposes the place particulates are suspended in course of flows, and/or the place pigging is required for cleansing and maintenance.
เกจวัดแรงอัดกระบอกสูบ are provided in sizes from 2–12 in, with American Society of Mechanical Engineer (ASME) flange scores of Class a hundred and fifty, 300 and 600. Pressure rankings match the flange ranking sizes, and the maximum temperature is 700°F (371° C).
