Emerson Process Management has introduced a range of Rosemount® 9901
chambers, allowing external mounting of level measurement and control
instrumentation on process vessels. It was developed from the existing
range of Emerson’s Mobrey® chambers, offering a European Pressure
Equipment Directive 97/23/EC (PED) compliant design in accordance with
ASME B31.3.
External mounting of level instrumentation allows isolation for
maintenance or calibration. It can also act as a stilling chamber for
turbulent liquid surfaces and enables instrumentation of vessels with
such internal structures as tube bundles.Emerson Process Management
