Patent ID: 7343775

Claim:
A gas test system ( 300 ), comprising: a flow loop ( 302 ) configured to contain a pressurized gas; a temperature control system ( 306 ) coupled to said flow loop and configured to contol the temperature of said pressurized gas; a reference meter system ( 308 ) coupled to said flow loop and configured to measure a property of said pressurized gas; and a unit under test system ( 310 ) configured to connect a unit under test to said flow loop to allow said unit under test to measure a property of said pressurized gas; said gas test system being characterized by: a blower system ( 304 ) having an inlet ( 321 ) and an outlet ( 322 ) and configured to receive said pressurized gas at said inlet, and generate a high flow rate of said pressurized gas out of said outlet to circulate said pressurized gas through said flow loop, wherein the blower system generates a low pressure rise from said inlet to said outlet in generating said high flow rate.
