Mass flow tightness testing on production line

The SDT LeakTESTER is an electronic measurement unit equipped with mass flow sensors. It is used for either manually or automatically simultaneously checking the tightness of between one and eight elements - generally at the end of a production line - with rigid tightness criteria (taps, catheters, pouches, bottles, packaging, bottle, syringes, cartridges, cooling circuits, shock absorbers, etc.).

The measurement of tightness is carried out by measuring the rate of flow of gas (air, nitrogen, etc.) and not by the difference in pressure between the reference volume and the piece being tested. This measurement (SCCM) is carried out by passing the flow through a mass flow sensor.
