摘要： PROBLEM TO BE SOLVED: To provide a gas shut-off device achieving high gas consumption measuring precision, and providing advantages for cost of gas for users. SOLUTION: As a flow detecting means 19 detects gas flow, it is converted into a flow signal to be outputted, and periods till next output of the flow signal are measured by a period measuring means 20. A period determining means 22 determines if periods measured by the period measuring means 20 is over periods set by a period setting means 21 by a prescribed flow or not. When it is, a time counting means 23 starts counting time. When a time determining means 25 determines that a lower limit time set by a time setting means 24 is exceeded, a flow value converted by a flow converting means 26 is integrated by a flow integration means 27.
