INSTRUMENT MONITORING DEVICE |
摘要 |
PROBLEM TO BE SOLVED: To discover a trouble particular to a specific gas instrument while the trouble still remains in a minor state. SOLUTION: An instrument monitoring device is equipped with: a flow rate detection part 102 for detecting the gas flow rate in a gas passage; a flow rate calculation part 103 for calculating a flow rate value based on a flow rate detection signal; an information obtaining means 107 for obtaining specific information during a period when gas is used; an instrument discriminating part 105 for discriminating a specific gas instrument from the specific information obtained by the information obtaining means 107 and the flow rate value of the flow rate calculation part 103; a specific event determination value setting part 111 for adding prescribed change amounts to the flow rate value and the specific information, respectively, and setting a determination value; a specific event monitoring part 110 for monitoring the flow rate value and the specific information when the specific instrument is discriminated by the instrument determination part 105; and a specific event determination part 109 for determining that a specific event has occurred when a monitor value of the specific event monitoring part 110 exceeds the set value of the specific event determination value setting part 111.
