Flow-X Series Flow Computer Evaluation Certificate

This document is an evaluation certificate and description for ABB's Flow-X series flow computers (models Flow-X/M, Flow-X/P, Flow-X/S, Flow-X/R), which serve as calculating and indicating devices for electronic gas-volume conversion (EVCD) using the PTZ conversion principle. It outlines the device's compliance with WELMEC guides and European standards, its modular design, environmental specifications, and the various enclosure configurations for different mounting applications.
