“…The unusual detected effect is probably related to the device, in fact in the framework of EMRP IND12, several measurements have been performed with different kind of leaks: in all the cases, the results, at low inlet pressures, highlight the typical behaviour of molecular regime, confirming that the flowmeter works properly [15].…”

“…The upstream pressure is controlled by means of a pressure controller. The leak conductance depends on and the leak temperature via a temperature coefficient which absolute value is about 0.1-0.3 %•K -1 [5]. The generated molar flow rate can be written as:…”

Volume calibration using a comparison method with a transfer leak flow rate

2020

This paper describes a volume comparison method carried out under a fine/rough vacuum using a small transfer flow rate from a capillary leak artefact. This method is suitable for volumes of vessels with complex shapes such as tubing arrangements equipped with various pneumatic parts (valves, gauges …), sample volumes, etc. The calibration, based on pressure rise measurements performed with a constant-volume flowmeter set-up, exhibits a standard relative uncertainty between 0.03 % and 2 % for volumes ranging from 1 to 3000 cm³, which is only about one order of magnitude higher than capabilities of the gravimetric volume calibration.

“…At present, crimped capillary leaks and orifices are often used to restrict the tracer gas flow and generate a leak rate [1][2][3]. However, it is difficult to further decrease the gas flow because the minimum feature dimension of the leaks is above one micron.…”
