9901 family of chambers

The 9901 family of high-quality chambers enables external mounting of level measurement and control instrumentation on process vessels. External mounting allows easy isolation of a particular instrument for routine maintenance or calibration, as well as for the fitting of instrumentation to vessels having internal structures. The units can also act as stilling chambers for liquid surfaces that are prone to turbulence. The chambers’ design is fully compliant with the European Union’s Pressure Equipment Directive (PED) and the American Society of Mechanical Engineers (ASME) B31.3 standard. They are available simply as chambers for use with existing instrumentation, as well as via an integrated bolt-on instrumentation solution from the manufacturer. Standard chamber selections include carbon steel or stainless steel, with diameters of 3 in. (80 mm) or 4 in. (100 mm). A wide choice of process, drain and vent connections is offered to minimize fitting costs.
