                                                                    產品簡介

                                                                     CG-L-2.5/4.0/6.0系列IC卡燃氣表,,是以膜式燃氣表為基表,以邏輯加密卡為媒體,加

                                                                     裝電子控制器(ECU)所組成的一種具有預付費功能的燃氣計量裝置。燃氣公司無需

                                                                     上門抄表打擾用戶,并可實現“先收費、后用氣”,使經營管理更加簡化。

                                                                     結構及工作原理

                                                                     在膜式燃氣表計數器,,的0.01m3字輪“0”處嵌入一顆永磁鐵,兩只干簧管繼電器呈180o

                                                                     安裝在字輪附近,字輪每旋轉一周,產生2個脈沖,為一個完整的脈沖信號,代表0.1 m3

                                                                     體積流量,由此實現機-電信號實時轉換。利用IC卡向表內充入預購氣量,當總用氣量等

                                                                     于總購氣量時,內置控制閥關閉以達到停止供氣的目的。
