Description

Technical Field

[0001] The utility model relates to the technical field of flow meter calibration, in particular to a flow meter calibration device for chemical industry. Background Art

[0002] Flow measurement is one of the components of metrology science and technology. It is closely related to the national economy, national defense construction, and scientific research. Especially in today's era of energy crisis and increasingly automated industrial production, the status and role of flow meters in the national economy are more obvious. In the chemical production process, it is crucial to measure the liquid flow in the transmission pipeline. The existing chemical pipeline uses a single flow meter for measurement during liquid flow measurement, and it is impossible to compare the measurement data at the same pipeline. At the same time, the existing flow meters mostly measure by adding pipeline diversion. Since the pipe size of the measuring part of the added pipeline is greatly different from the original pipe inner diameter when in use, pressure changes are likely to occur during the liquid flow process, which leads to measurement errors in the flow meter during the measurement process. Therefore, we need to effectively calibrate its equipment, so we design a flow meter calibration device for chemical industry. Utility Model Content
