一、流量自动记录仪我们从一九八○年开始研制野外测流仪表,即LL—I型流量自动记录仪。仪器由两个部分组成:(1)标定管测流装置。(2)流量自动记录。其测流原理是:当流体通过标定管时,便产生瞬间特征流速,再利用接在管外测压口三通上的自动记录仪把流速Ⅴ随着时间t的变化过程线,连续不断地记录下来,并在记录仪的仪表盘上显示出瞬时流量。 First, the flow of automatic recorder We began in 1980 developed field measuring instrument, that is, LL-I-type flow recorder. The instrument consists of two parts: (1) Calibration tube flow measurement device. (2) Automatic flow recording. The principle of flow measurement is: When the fluid passes through the calibration tube, it will produce instantaneous characteristic flow rate, and then use the automatic recorder connected to the pressure measurement port on the outside of the tube to change the flow rate of the flow rate V with time t, continuously. Record and display instantaneous traffic on the recorder’s dashboard.
