Device for calibrating fluid measuring device

The utility model provides a device for calibrating a fluid measuring device, which comprises a bearing assembly, a first pipeline arranged on the bearing assembly, and a standard flow part arranged on the first pipeline and provided with a connecting part used for being connected with a measured instrument, the volume metering component is arranged on the first pipeline and is provided with a feed port and a discharge port, and the feed port is communicated with the first pipeline; and a fluid control part is arranged on the first pipeline. According to the scheme, the measured instrument is calibrated by combining the standard flow part and the volume metering part, and calibration can be completed without frequently injecting liquid during calibration, so that more time and labor are saved. 本实用新型提供了一种对流体测量装置进行校准的装置，包括承载组件、设置在所述承载组件上的第一管道，以及标准流量部件，设置在所述第一管道上，且存在一连接部，用于连接被测仪表；体积计量部件，设置在所述第一管道上，且存在一进料口与一出料口，所述进料口与所述第一管道相通；所述第一管道上设置有流体控制部件。本方案采用的是标准流量部件与体积计量部件相结合的方式来校准被测仪表，在校准时无需频繁注入液体即可完成校准，更为省时省力。
