一、概述我厂校验各式气体流量计是采用传统的操作方法,即用钟罩式(又称浮筒式)气体流量标准装置作为标准容器,在校验时配合秒表,管路联接(见图1)。由一人操纵调节开关1,按被校流量计2的某一校验点保持流量恒定,气流经流量计2、导管8旋入浮筒4,使浮筒均恒上升,带动刻度盘6进转(刻度盘的刻线是按浮筒的容积进行定度的,以升为单位);由另一人用秒表选定并记录浮筒在一定容积范围内此V_1到V_2的运动时间t,然后按定义公
First, an overview of our factory calibration of all kinds of gas flow meter is the traditional method of operation, that is, bell-style (also known as buoy) gas flow standard device as a standard container, with the stopwatch in the calibration, piping connections (see figure 1). By a person to manipulate the adjustment switch 1, according to be calibrated flow meter 2 check point to maintain a constant flow, air flow through the flow meter 2, the catheter 8 screwed into the buoy 4, so that buoys are constantly rising, driven by the dial 6 (scale The engraving of the plate is determined by the volume of the pontoon in liters; the other person selects and records the movement time of the pontoon V_1 to V_2 within a certain volume by the stopwatch, and then, according to the definition of the male
