Abstract:
PROBLEM TO BE SOLVED: To accurately detect leakage or the like based on pressure and flow rate when a fluid is used. SOLUTION: A flow rate measuring unit 106 measures the flow rate of a gas flowing through a flow path 102, while a pressure measuring unit 108 measures the pressure. An analysis unit 112 inputs the measured flow rate data and pressure data, and analyzes the flow rate change following the pressure change. A flow rate change amount corresponding to a pressure change amount at a predetermined level or higher is classified into multiple ranges based on predetermined thresholds, and it is determined whether the flow rate changes following the pressure change based on determination conditions depending on the range of the flow rate change.

PROBLEM TO BE SOLVED: To solve the problem, wherein new instrument information cannot be registered when the number of registrations reaches an upper limit, if the number of the registerable instrument information is restricted by the upper limit, even if there are instrument information that are no longer necessary, in the registered instrument information. SOLUTION: A flow rate measuring apparatus includes a storage memory 8 as a flow rate information storage means; and a registered instrument information removing means 11 for selectively removing the registered instrument information stored in the storage memory 8 and satisfying predetermined conditions. Even if the number of the registered instrument information reaches the upper limit, the instrument information no longer necessary can be removed, and the new instrument information can be registered, in place of the instrument information removed.

Abstract:
PROBLEM TO BE SOLVED: To prevent wrong determination due to a change caused by aged deterioration in discriminating a gas appliance according to flow information, because although it is general to utilize the flow characteristics peculiar to the appliances in discrimination, the peculiar flow characteristic varies with each appliance so that wrong determination is caused by discriminating the gas appliance using one flow characteristic. SOLUTION: This flow measuring device includes: a flow measuring part 7 for measuring a flow of a fluid flowing through a passage; a measured flow value measured by the flow measuring part; a flow information storage part 8 storing object data describing the measured flow value corresponding to the measurement time; and an object data classifying part adapted to take the first object data stored in the flow information storage part as a reference data and classify a second object data into groups by each reference databased upon a coefficient of correlation showing the relationship between a measured flow value of the second object data and a flow value of the reference data.
