燃气表是燃气能源计量的主要计量器具,其质量优劣涉及供需双方利益,计量行政机构、制造单位、供气企业都非常重视燃气表的产品质量。传统的膜式燃气表需要抄表人员定期挨家挨户抄取数据,结算出费用后,再到各家收费,误差大、统计工作量大,人为的错误给物业管理和用户带来极大不便。随着城市燃气的发展以及人民生活水平的提高,燃气居民用户数量逐年增加,抄表难、收费难困扰着众多的燃气公司,抄表人员的不断增加提高了燃气公司的经营成本,也给管理带来许多不便。随着电子技术、网络信息技术发展日新月异,在国家相关政策的推动下,燃气表智能化已是大势所趋,IC 智能燃气表应运而生,发展势头迅猛,目前我国处于传统燃气表向IC卡智能燃气表的转换阶段。

智能气表具有自动收费功能,一户一表一卡,用户将费用交给管理部门,管理部门将购气量写入IC卡中,用户将IC卡中信息输入智能燃气表中,智能燃气表便自动开阀供气。在用户用气的过程中,智能燃气表中微电脑自动核减剩余气量,所购气量用尽,智能燃气表自动关阀断气,用户需重新购气方能再次开阀供气。 IC卡还能记录智能燃气表的运行情况,在管理机或管理软件下将表的总用气量、总购气量、开关阀状态等信息进行管理。智能燃气表可以提高管理效率,有效防止欠费,避免上门抄表,实现节约用气。适合用于天燃气、煤气等流量的计量。 带漏气报警功能的智能燃气表可以监测室内可燃气体的泄漏,当室内可燃气体泄漏时,该燃气表的可燃气体探测器会发出声光提示,智能燃气表的液晶屏会显示报警信息,并自动关闭阀门。
