eFlo - electronic flow meter

eFlo is an electronic flow measurement instrument used to display and control the flow of gases. With simple compatibility with existing controls, tracking an monitoring gas flows has never been easier. Designed for use in the harshest industrial enviroments.

eFlo allows for easy replacement of manual flow meters and seamlessly integrates into existing control systems.
