| Abstract |
A device for producing standard diluted gas mixtures in which the constant flow rate is maintained by gaseous viscosity is described. The driving pressure difference is derived from a frictionless mercury ring piston. The device represents a volumetric primary standard. At the same time, it is also a secondary standard, as the flow rate is known by reference to well-known constants: gas viscosity, cubic dilation constant of mercury, and mass and length measurements. The apparatus is distinguished by its very simple design and relative insensitivity to temperature variations. |
