Foxboro CFS300A / CFS400A / CFS700A Coriolis Flowmeter

CFS Series Flowmeters

The Foxboro CFS Series (CFS300A, CFS400A, and CFS700A) represents a high-performance family of Coriolis mass flow sensors from Schneider Electric, designed to deliver direct, accurate, and reliable mass flow and density measurements across a wide range of industries and process conditions. Leveraging advanced Coriolis technology, these sensors are capable of simultaneously measuring mass flow, density, temperature, and volume flow, with excellent repeatability and real-time diagnostics. Whether the application is basic process control, custody transfer, or harsh chemical measurement, Foxboro’s CFS series delivers the right balance of performance, robustness, and application-specific customization.
