| Abstract: | 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. |
