Overview
The ATEQ MF570 is a differential micro flow tester combining fast cycle times with high-accuracy leak measurement. It uses differential pressure drop and stable flow measurement via a laminar flow element. The measurement element is fully integrated in a single module and the unit supports SI, USA (SAE) and custom units, with ambient temperature and atmospheric pressure indication.

Technology
The Mass Flow technology converts the mass of air through a laminar flow element into a leak value (e.g. cm3.atm/h). The design handles large-leaking parts on the line without requiring a reset and avoids heating elements to measure air mass, reducing sensitivity to contamination. The unit supports test pressures up to 20 bar (300 PSI) and integrates temperature compensation for improved accuracy under varying conditions.
