Emerson has launched the Fisher WhisperTube Modal Attenuator for noisy fuel or vapour applications, which offers noise discount in compressible fluid service for improved employee security, with no impact on process circulate.

The modal attenuator from Emerson is a full-bore device providing 15-decibel sound suppression to reduce noise inside pipes produced by sources upstream, such as management valves or different devices. It is installed downstream of these units in place of a pipe spool piece, it generates no additional strain drop, and has no influence on course of circulate.
Until now, all solutions have generated significant strain drop, decreased circulate, and/or introduced obstructions. This has led some customers to put in acoustic insulation to pipe sections to reduce noise, but this could be costly and cumbersome to put in, and it does nothing to reduce inside piping noise. เกจวัดแก๊สหุงต้ม addresses these and other points with a drop-in solution, improving employee safety and regulatory compliance, whereas reducing the risk of injury to downstream tools as a end result of excessive noise ranges inside to piping.
Leading purposes for the modal attenuator embody these the place upstream course of flows are changed by control valves, strain reduction valves, pumps, compressors and different units that generate noise. Many of these devices have to be installed in lengths of piping with no move restrictions downstream, and the modal attenuator works nicely in these functions as a end result of it introduces no such restrictions.
In addition, the modal attenuator does not introduce an obstruction into the piping, so it can be used in functions the place particulates are suspended in process flows, and/or where pigging is required for cleaning and upkeep.
WhisperTube units are provided in sizes from 2–12 in, with American Society of Mechanical Engineer (ASME) flange rankings of Class one hundred fifty, 300 and 600. Pressure scores match the flange score sizes, and the maximum temperature is 700°F (371° C).
