摘要： PROBLEM TO BE SOLVED: To provide a check system of slight gas delivery amount which can detect precisely slight leakage of gas from a gas conduit in gas supply equipment or the like. SOLUTION: A check system 1 of midnight slight gas delivery amount is equipped with a normal gas supply path passing a normal gas meter 23 and a gas supply path for leakage detection passing a small-sized gas meter 25 for leakage detection which has high sensitivity, in a gas supply system 3. The gas supply paths are switched over with an actuator valve 21 controlled by a control board 27 including a timer switch. In a time zone from midnight 2 to 3, gas is made to flow through the gas supply path for leakage detection, and an integrated value of a gas flow rate is obtained by using the gas meter 25 for leakage detection. Since the integrated value of a slight gas flow rate can be measured precisely, it can be judged precisely on the basis of the integrated value whether slight leakage of gas from the gas conduit exists.

摘要： PROBLEM TO BE SOLVED: To provide a meter checking data communication system for remotely checking meter reading data by means of an inexpensive structure. SOLUTION: A gas meter checking data communication system 1 is provided with an electronic gas meter 2 with a built-in ID tag 20 and an ID tag reader 3. In comparison with a system remotely reading meter reading data of a gas meter via communication by means of a general communication apparatus, this system can be constructed at very low costs because of low cast of the ID tag 20. In addition, low power consumption prolongs a battery life.

摘要： PROBLEM TO BE SOLVED: To provide a vessel inspection method and its device executed during a period when temperature in a vessel is exponentially lowering like a period after repairing a pipeline by an airflow lining construction method, etc., and to enhance the efficiency of repair work and of inspection work after repair. SOLUTION: Since the inside and outside temperatures of the vessel are different and a leak from the vessel is inspected by means of a pressure higher than a pressure outside the vessel, the pressure in the inspected vessel is increased or decreased at a pressure higher than the pressure outside the vessel. A pressure difference X i between the vessel outside and the vessel inside at at least three different time points t i (i=1, 2, and 3) and the rate Y i of change in temperature with time of the pressure in the vessel are measured. The pressure difference X i and the rate Y i of change measured in this pressure state measurement process are applied to the following expressions to calculate a leak constant L related to leak: Y 1 +aY 2 +bY 3 =-L(X 1 +aX 2 +bX 3 ), where, a=γ/(1-γ), b=1/(γ-1), t 3 -t 1 =γ(t 2 -t 1 ). A leak from the inspected vessel is detected based on the leak constant L. COPYRIGHT: (C)2007,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an integrator for a gas flow rate capable of calculating an integration value in each flow rate division of the gas flow rate with an error within a calibration tolerance of a gas meter. SOLUTION: This gas flow rate integrator 10 is provided with an ultrasonic gas meter 11 and an electronic integration value counter 12. An momental value of the gas flow rate is detected by the ultrasonic gas meter 11, and the integration value of the respective flow rates or the gas flow rates in the respective flow rate divisions is calculated by tire counter 12 based thereon. The gas flow rate is determined in a moment, and the integration value is calculated accurately with the error within the calibration tolerance of the gas meter, because the detected gas flow rate is supplied directly to the electronic integration value counter 12.

摘要： PROBLEM TO BE SOLVED: To provide an electronic city water meter in which the visibility of a liquid crystal display part is excellent even in a dark place, and the generation of an abnormality in city water pressure and the like is confirmable without opening the meter lid. SOLUTION: This electronic city water meter 1 is enhanced in the visibility for the meter in a dark box and a shaft, since the meter 1 has a lighting part 5 for lighting the liquid crystal display part 3. Since electric power supply to the lighting part 5 is controlled by an electric power source control part 6 based on opening and closing of the meter lid 4, the display part 3 is lighted only by opening the meter lid 4 without conducting a manual operation. The meter is thereby read without lighting a display face by a luminair and the like. In abnormal display in the city water pressure, the lighting part 5 is flickered by the power source control part 6 to judge the abnormality easily. This flickering for an abnormality can be visually confirmed without opening the meter lid 4 by making the meter lid 4 transparent.
