摘要
介绍燃气表流量感知技术、燃气表安全切断技术以及燃气流量区间划分和安全切断条件。将燃气流量划分为异常小流量、正常流量超长时间使用和异常大流量3类区间,给出各流量区间的具体划分参数以及对应的安全切断前持续时间。
Gas meter flow sensing technology, gas meter safety cut-off technology, gas flow interval division and safety cut-off conditions are introduced. The gas flow is divided into three types of intervals in- cluding abnormal small flow, normal flow used over- time and abnormal large flow. The specific partition parameters of each flow interval and the corresponding duration time before safety cut-off are given.
