Emerson Process Management has introduced a range of chambers that allow for the external mounting of level measurement and control instrumentation on process vessels. The 9901 chamber range, which has been adapted and extended from the existing range of Mobrey chambers, offers a standardized, fully PED (Pressure Equipment Directive) compliant design in accordance with ASME B31.3.
External mounting of level instrumentation is often preferred by users, as it allows for easy isolation of the instrument for routine maintenance or calibration, and acts as a stilling chamber for liquid surfaces prone to turbulence or fitting of instrumentation to vessels with internal structures such as tube bundles.
Using only certified and traceable materials, the 9901 series is manufactured using full penetration welds, with welders and welding procedures qualified to both ASME and European standards. All chambers are hydro tested on completion, with a full range of NDT or customer inspection options available to order.
Standard chambers are available in carbon steel or stainless steel in 80-millimeter or 100-millimeter diameters with centers of up to six meters. A choice of process, drain and vent connections is offered to minimize fitting costs. Other materials, including exotic alloys, are available upon request.
