摘要
控制器配合煤气表的传感装置、磁卡和断气装置，可进行定量计量、报警、断气等功能．多次反复实验结果表明，控制器使用ＣＭＯＳ集成电路，能准确实现清零、预置初值、减计数、声光报警及断气显示等功能．
Cooperated by a gas meter
sensor,a magnetic card,and a cut off device,thecount controller,whose circuit consists of CMOS
integrated components,possesses suchfunctions as gas quantitative measuring,warning and gas
cutting off,etc..Lots of repeatedtests show that the controller acts accurately for resetting,presetting
an initial value,count-ing-down,acoustooptical alarming,and displying gas cut-off.
