Product Overview
Thermal mass flow meters and controllers provide precise gas flow measurement and control using heat‑transfer technology. They directly measure mass flow without additional temperature or pressure compensation, offering high accuracy, fast response, and excellent repeatability. Flow controllers add an integrated control valve, enabling automatic closed‑loop regulation for precise dosing or mixing. These instruments support a wide range of clean gases across micro‑flow and industrial capacities. With optional analog and digital outputs, they integrate easily into automated systems. Used in laboratories, manufacturing, combustion optimization, and gas distribution, they deliver stable, efficient performance with minimal maintenance.
