    摘要: A gas test system (300) is disclosed comprised of a flow loop (302), a blower system (304), a temperature control system (306), a reference meter system (308), and a unit under test (UUT) system (310). The UUT system connects a unit under test (UUT) to the flow loop. The blower system receives the gas under pressure at an inlet (321), and generates a high flow rate of the gas out of an outlet (322) while generating a low pressure rise from the inlet to the outlet. The temperature control system receives the flow of gas from the blower system and controls the temperature of the gas. The reference meter system and the UUT in the UUT system measure a property of the gas circulating through the flow loop. The measurements of the reference meter system can be compared to the measurements of the UUT to calibrate the UUT.
