Emerson has launched the Fisher WhisperTube Modal Attenuator for noisy fuel or vapour applications, which offers noise discount in compressible fluid service for improved worker safety, with no influence on process move.

The modal attenuator from Emerson is a full-bore gadget providing 15-decibel sound suppression to scale back noise inside pipes produced by sources upstream, corresponding to management valves or different gadgets. เกจวัดแรงดันเชื้อเพลิง is put in downstream of these gadgets in place of a pipe spool piece, it generates no further pressure drop, and has no impact on process circulate.
Until now, all solutions have generated important stress drop, lowered move, and/or launched obstructions. This has led some users to put in acoustic insulation to pipe sections to minimize back noise, but this can be expensive and cumbersome to install, and it does nothing to reduce inner piping noise. The modal attenuator addresses these and other issues with a drop-in resolution, improving employee security and regulatory compliance, whereas lowering the danger of harm to downstream tools because of high noise ranges inner to piping.
Leading เกจวัดแก๊สหุงต้ม for the modal attenuator include these where upstream course of flows are modified by management valves, pressure reduction valves, pumps, compressors and different devices that generate noise. Many of these devices should be put in in lengths of piping with no flow restrictions downstream, and the modal attenuator works well in these purposes because it introduces no such restrictions.
In addition, the modal attenuator does not introduce an obstruction into the piping, so it may be utilized in functions the place particulates are suspended in course of flows, and/or where pigging is required for cleansing and upkeep.
WhisperTube devices are provided in sizes from 2–12 in, with American Society of Mechanical Engineer (ASME) flange rankings of Class a hundred and fifty, 300 and 600. Pressure rankings match the flange score sizes, and the maximum temperature is 700°F (371° C).
