南京炼油厂油品外运装油作业原用汽车灌装计量设备,精度低、计量误差大;装油作业劳动强度大.厂科技处、计量站会同南京电讯仪器厂,将微机技术应用于油品出厂的计量,收到了满意的效果.该项技术改造全部采用国产设备,计量部分采用重庆仪表厂生产的腰轮流量计和南京电讯仪器厂生产的NK-05型微机.其原理是将腰轮转动的脉冲信号送入微机计数,同时油品温度信号通过温度变送器也送入微机.因为在微机内存中油品密度是
Nanjing Refinery Oil Sinter oil filling operation Original car filling measuring equipment, low accuracy, large measurement error; loading operation labor intensity. Plant Science and Technology Department, Metering Station in conjunction with Nanjing Telecommunications Instrument Factory, the microcomputer technology used in oil The factory’s measurement, has received satisfactory results.The technical transformation of all the domestic equipment, measuring part of the use of Chongqing Instrument Factory production of wheel flow meter and Nanjing Telecommunications Instrument Factory production of NK-05 type microcomputer.The principle is to waist Rotating pulse signal into the computer count, while the oil temperature signal through the temperature transmitter also into the computer because the memory density in the computer is
