GAS FEED AND MANAGEMENT DEVICE

摘要

PROBLEM TO BE SOLVED: To provide a gas feed and management device that reduces the replacement frequency of gas cylinders and improves their replacement work efficiency. SOLUTION: Gas cylinders 11a and 11b on a consumer 10 are united in operation by means of a gas feed line 12 that feeds LP-gas into a gas consumption pipe line 14 via a gas meter 13. The gas meter 13 detects gas consumption from a time point when the gas cylinders 11a and 11b are simultaneously replaced as a cumulative gas consumption and transmits the data to a management center 30 via a wireless network 20, a relay 21 and another wireless network 22. The gas meter 13 also detects a gas residual capacity from the initial charge and gas consumption of the gas cylinders 11a and 11b and sends an alarm signal corresponding to the gas residual capacity to the management center 30. A processor 31 in the management center 30 computes gas consumption per month of each consumer 10 from the gas consumption the gas meter 13 sends thereto, and notifies the operator to replace the gas cylinders 11a and 11b in response to the alarm signal.
