Better measurements, greater control

For a major seal manufacturing company, it was a classic case of not being able to control what it could not measure. The manufacturer planned to install a brand-new boiler in its steam system, but could not precisely calculate how much steam was needed to drive its manufacturing processes.

At Spirax Sarco’s recommendation, the manufacturer installed an inline vortex flowmeter at a critical location. The meter’s highly accurate measurements convinced the company to downsize from a 25,000-lb. boiler to a less expensive 15,000-lb. boiler. The manufacturer realized major savings while maintaining its production efficiency.

Bottom line: Better measurements lead to cost savings and greater control.

Target Variable Area (TVA) Meter

The Target Variable Area (TVA) Meter is specifically designed for accurate measurement in saturated steam applications. Its critical surfaces resist erosion caused by water droplets. For proper installation, the TVA requires only a short length of straight piping—six pipe diameters upstream and three diameters downstream from the meter.

The TVA’s built-in density compensation feature provides accurate measurements without a separate flow computer.

Additional specs:• Available in 2”, 3” and 4” sizes (DN50, DN80, DN100)• 50:1 turndown ratio provides accuracy over a wide flow

easy viewing of indicators such as flow rate, total flow, pressure and temperature.

Inline Variable Area (ILVA) Meter

The Inline Variable Area (ILVA) Meter accurately measures widely varying flows, making it ideal for applications where flow rate fluctuates throughout the year. It is suitable for all types of industrial fluids.

The ILVA meter can be installed in confined spaces because it needs only six pipe diameters upstream from and three diameters downstream from the meter. A mechanical stop prevents damage from over-ranging or reverse flows. It can handle horizontal and vertical down flows.

The ILVA’s compact design, installed between two flanges, provides outstanding performance in a small footprint.

Additional specs:• Accuracy: 1.0% of flow rate (between 100% and 5% of
