GAS LEAK INSPECTION SYSTEM

摘要

PROBLEM TO BE SOLVED: To provide a gas leak inspection system capable of judging immediately and in a short time the gas leak occurring in supply side or use side in a gas concentration supply system and realizing with an easy work exactly monitoring whether or not the gas use state is safe. SOLUTION: A gas leak inspection device 17 is constituted of a leak inspection transmission/reception means 23 transmitting leak inspection demand signal to a master radio transmission/receiver 18 and receiving a flow velocity signal from a slave radio transmission/receiver 19, a flow velocity integration means 24 for obtaining instantaneous flow with the total of the received velocity signals, a velocity detection means 21 for measuring signal transmission time in gas flow path and detecting the flow velocity, a flow operation means 22 for obtaining instantaneous flow with the detected velocity signals, a leak judging means 25 for comparing the flow rate in supply side and total flow rate in use side and judging gas leak or not and an informing means 16 for informing the leakage when judged.
