针对当前小流量控制及检测方面的研究现状,立足于工业生产的需求和提高计量能力的需要,建立了一套气体小流量标准装置。该装置包括活塞式气体流量标准装置、电子皂膜气体流量标准装置和标准表法气体流量标准装置,可涵盖(0.01~3 000)L/min的流量范围,准确度等级分别达到0.05级、0.4级和0.5级,满足了气体小流量计量项目的量传要求。
In view of the current research status of small flow control and detection, based on the needs of industrial production and the need to improve the measurement capability, a set of gas small flow standard device was established. The device includes a piston gas flow standard device, an electronic soap film gas flow standard device and a standard meter gas flow standard device, which can cover the flow range of (0.01-3000) L / min and the accuracy grades reach 0.05, 0.4 Level and 0.5, to meet the small amount of gas measurement project mass transfer requirements.
