摘要： PROBLEM TO BE SOLVED: To provide a gas meter employing a multistage sensing type earthquake sensor outputting a different signal corresponding to the intensity of a sensed earthquake and capable of controlling the cutting-off of gas corresponding to the intensity of a detected earthquake. SOLUTION: A gas cut-off controller 7 performs the cut-off control of gas so that a generated earthquake is regarded as a small one to perform the restorable cutting-off of gas, when only a first stage pulse signal is generated within a specific period according to incorporated gas cutting-off logic on the occurrence of an earthquake. The generated earthquake is regarded as a big earthquake when first and second stage pulse signals are generated to perform the non-restorable cutting-off of the gas. The generated earthquake is regarded as a shock when only the second stage pulse signal is generated to perform no cutting-off of the gas. By this constitution, the non-restorable immediate cutting-off of the gas is not performed by an insignificant earthquake and, when a person touches with gas piping or beats a carrying cargo against the gas piping, the immediate cutting-off of the gas by erroneous operation is prevented.
