digital pressure gauge has launched the Fisher WhisperTube Modal Attenuator for noisy fuel or vapour functions, which presents noise reduction in compressible fluid service for improved employee safety, with no impact on course of circulate.

The modal attenuator from Emerson is a full-bore device providing 15-decibel sound suppression to scale back noise inside pipes produced by sources upstream, corresponding to management valves or other units. เกจวัดแรงดัน is installed downstream of these units instead of a pipe spool piece, it generates no extra stress drop, and has no impact on process flow.
Until now, all options have generated vital stress drop, reduced flow, and/or introduced obstructions. This has led some customers to install acoustic insulation to pipe sections to reduce noise, however this can be costly and cumbersome to install, and it does nothing to scale back inside piping noise. The modal attenuator addresses these and other points with a drop-in resolution, improving worker safety and regulatory compliance, while decreasing the chance of injury to downstream tools as a end result of excessive noise levels inner to piping.
Leading applications for the modal attenuator include those where upstream course of flows are changed by control valves, pressure aid valves, pumps, compressors and different devices that generate noise. Many of those gadgets must be put in in lengths of piping with no circulate restrictions downstream, and the modal attenuator works well 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 can be utilized in functions where particulates are suspended in process flows, and/or where pigging is required for cleaning and maintenance.
digital pressure gauge are offered in sizes from 2–12 in, with American Society of Mechanical Engineer (ASME) flange ratings of Class one hundred fifty, 300 and 600. Pressure ratings match the flange score sizes, and the utmost temperature is 700°F (371° C).
