Gas Flow Sensors / Standards

patentThe Intelligent Gas Flow Sensor (IGFS) and Standard offer solutions for complex flow measurement challenges using ATC’s ALF technology (Accelerated Laminar Flow). Our Micro-Flow Technology for leak testing and calibration has introduced a new dimension in the area of micro-fluid dynamics.
