G620

COMPACT LEAK TESTER WITH CONTINUOUS FLOW

A high-performance, continuous-flow leak tester built into a compact format—ideal for automatic or semi-automatic production lines. It’s one of the smallest units with full-feature capabilities, enabling real-time leak localization and repair thanks to its continuous-flow mode.

Perfectly suited for testing small-volume parts—such as automotive injection components, filter caps, gas fittings, burners, and heat-exchanger items—on production lines.

TECHNOLOGY

CONTINOUS FLOW TEST PRINCIPLE

When the part under test 6 is connected to the device 1, the internal tank 2 is pre-filled at the test pressure and then, it moves through a calibrated flow tube 3 which causes a drop in pressure. The pressure drop is measured by a differential pressure sensor 4. The pressure of the part under test 5 is measured by the sensor 5.

Diagram showing the continuous flow measurement principle of an ATEQ flow tester

Often considered as a competitor to the Mass Flow technology, continuous flow relies on a differential pressure transducer and a very precise laminar flow tube to measure leak rates. Its internal volume ensures that the flow generated by the leak remains very stable over time.

This technology is perfectly suited to the gas industry which sees it as a real time leak reader for gas appliances on production lines. While the instrument generates a leak and shows its value on the screen, the operator can tighten the connections of the gas product until it reaches an acceptable leak rate.
