This device relies on the precise measurement of the pressure drop of a gas flowing through an orifice. Usually used for specific gasses (e.g. helium, hydrogen, nitrogen, air) used in laboratory analytical equipment, the pressure drops were measured by a delicate Magnehelic® device calibrated for flow rate. Manufactured by A. E. D. of Chicago.
