Abstract
An adapter to convert a traditional gas meter into a computerized gas meter is disclosed. The adapter of this invention comprises a microcomputer gas flow signal converting module, a gas flow monitoring module, a gas pressure monitoring module, an earthquake sensing module and a gas supply shutoff mechanism, and a casing to enclose the modules and to affixed to said traditional gas meter. The microcomputer gas flow rate signal converting module senses the movement of diaphragm of the traditional gas meter and converts the gas flow rate into computerized signals. The gas flow monitoring module and the gas pressure monitoring module monitor the gas flow rate and the gas pressure, and generate warning signals when abnormal phenomena are sensed. The earthquake sensing module senses strong earthquakes according to vertical vibration waves and horizontal vibration waves of said earthquake. The gas supply shutoff mechanism stops movements of diaphragm in order to stop gas supply when a warning signal is generated by said gas flow monitoring module, said gas pressure monitoring module or said earthquake sensing module.
