摘　　要：本液体密度测试仪以32位单片机STM32F103RC为核心控制器,通过三个气压传感器分别采集玻璃管不同状态的压强,利用控制器对采集的数据进行处理,结合液体压强公式,得到被测液体的密度和高度,并通过OLED液晶显示屏实时显示,对比于已有液体密度测试仪所采用的方法,本密度测量仪具有响应快、直接显示、携带方便等特点。The design of this liquid density tester uses the 32-bit single-chip microcomputer STM32F103RC as the core controller,by collecting the pressure of the glass tube in different states through three air pressure sensors,using the controller to process the collected data,and the density and height of the measured liquid can be obtained by utilizing the liquid pressure formula,which can be displayed on the oxide liquid crystal display in real time.By comparing with the existing liquid density test method,the design of this liquid density tester has the characteristics of responding quickly,displaying directly,carrying easily.
