Foxboro 84CW Wafer Vortex Flowmeter

84CW Vortex Flowmeter

The Foxboro 84CW vortex flowmeter is a rugged, industrial-grade device engineered to provide highly accurate and repeatable flow measurement of liquids, gases, and steam across a wide range of industrial processes. Designed with robustness, reliability, and ease of integration in mind, the 84CW leverages Foxboro’s decades of vortex metering expertise to deliver superior performance in demanding applications such as chemical processing, power generation, oil and gas, water treatment, and manufacturing.

At its core, the 84CW employs the well-established vortex shedding principle, which uses a bluff body inserted into the flow stream to generate alternating vortices. These vortices are detected by sensors that convert their frequency into a signal proportional to the fluid’s velocity. This technology is inherently reliable because it contains no moving parts, eliminating mechanical wear and reducing maintenance needs. The 84CW can measure volumetric flow with precision, and when equipped with optional temperature inputs and compensation algorithms, it can also calculate mass flow—a critical metric in steam or temperature-variable fluid applications.
