eFlo 2.0 Standard Flow Meters

eFlo 2.0 Standard Flow Meters

eFlo 2.0 is SSi’s newest electronic flow measurement instrument line. Like our previous eFlo models, the 2.0 line offers simple compatibility with existing controls, making tracking and monitoring gas flows easier than ever. Designed for use in the harshest industrial environments, eFlo allows for easy replacement of manual flow meters and seamlessly integrates into existing control systems.
