Micro-Flow Sensors

patentATC’s leak test instruments and calibration standards are built around our patented Micro-Flow Sensors. The Intelligent Gas Leak Sensor (IGLS™), the Intelligent Gas Flow Sensor (IGFS™) and the Intelligent Molecular Flow Sensor (IMFS™) are a range of revolutionary Micro-Flow Sensors using air for leak testing. The Micro-Flow Sensor is a part of ATC’s complete leak test instrument, and cannot be sold separately for leak testing applications.

The Micro-Flow Sensors offer solutions for complex flow measurement challenges using ATC’s accelerated laminar flow (ALF) technology and design based on Knudsen Flow phenomena. Our Micro-Flow Technology for leak testing and calibration has introduced a new dimension in the area of micro-fluid dynamics.
