MF520

COMPACT MASS FLOW LEAK TESTER

A compact, high‑precision mass-flow leak tester designed for quality control in production environments. Utilizing differential pressure-drop measurement combined with stable laminar flow sensing, it delivers fast and accurate leak and flow rate readings across 2, 20, and 200 ml/min ranges—with resolutions as fine as 0.01 ml/min and ±2.5 % accuracy. Other format include:

TECHNOLOGY

The Mass Flow technology converts a mass of air going through a laminar flow element into a leak value. Should the test part leak, a flow will take place between a reference part and this leak, forcing the air to go through the Mass Flow measuring device that will convert it into a leak value such as cm3.atm/h.

However, unlike traditional Mass Flows, our technology can handle “large leaking” parts on the line without having to reset the unit.

And unlike our competitors again, we do not use heating elements to measure the mass of air, thus reducing the sensitivity to contamination.

We’ve also put our expertise in high pressure testing into the pneumatics of this unit, allowing it to measure with a high level of accuracy at test pressures of up to 20 Bar (300 PSI).

Finally, our Mass-Flow technology comes with the latest temperature compensation feature making sure you get the best results in the industry in the toughest conditions.
