April 15, 2009 - New from Emerson Process Management is a range of high quality chambers which allows 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, allowing customers to buy an integrated bolt-on instrument solution from Emerson, or simply a chamber for use with existing instrumentation.

External mounting of level instrumentation is often preferred by users as it allows easy isolation of the instrument for routine maintenance or calibration, plus offers the additional benefit of acting 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. While the standard range is extensive and offers a cost effective solution, a custom design and build service is available for instances where the chamber must fit existing vessels or replace old products.

Standard chambers are available in carbon steel or stainless steel in sizes of 80mm (3”) or 100mm (4”) diameters with centers of up to 6m (19’ 8”).  A wide choice of process, drain and vent connections is offered to minimize fitting costs. Other materials, including exotic alloys, are available on request.
