Mass flowmeter measures rates of flow of all common gases from purges and collected leaks at leak ports. Without dependence on gravity, it measures rates between 5 and 650 cc/min with pressures ranging from 0.001 to 10 to the minus thirteenth torr at temperatures between 70 and 500 degrees K.
Leak detection for aerospace hardware, discussing equipment, operations, checkout, etc
Gas leakage rates are quantitatively estimated using threaded and flanged fittings by standardizing bubble appearance. Three classes of bubble formations have been proposed.

Positive displacement flowmeter for measuring extremely low flows of fluid with self calibrating features
Positive-displacement flowmeter measures low gas-flow rates by gaging the time required for a slug of mercury to pass between two reference levels in a tube of known volume.
