摘要： PROBLEM TO BE SOLVED: To provide an apparatus for judging the abnormality of a pressure sensor capable of accurately and inexpensively judging the abnormality of the pressure sensor alone, and a recording medium having a program for judging the abnormality of the pressure sensor recorded thereon.
SOLUTION: A cut-off valve 5 is provided on the upstream side of the pressure sensor 4 and a gas supply passage 2 toward the downstream side is cut off by closing the cut-off valve 5. When the cut-off valve becomes a closed state and the gas supply passage on the downstream side of the cut-off valve is opened, the pressure in the gas supply passage 2 becomes equal to atmospheric pressure. An abnormality judge means 1 judges the abnormality of the pressure sensor 4 on the basis of the comparison of the pressure signal S2 actually outputted by the pressure sensor 4 with the reference value of the pressure signal S2 to be outputted by the pressure sensor 4, when the pressure in the gas supply passage 2 is set to atmospheric pressure.

摘要： PROBLEM TO BE SOLVED: To accurately measure a flow rate by reducing influence of a pulsation flow by arranging flexible cylindrical members extending toward the downstream side from one of an inflow port and an outflow port.
SOLUTION: In a flowmeter 10, cylindrical members 15 are installed toward the downstream side in an inflow port 12 and an outflow port 13 arranged in a main body 11. These cylindrical members 15 are formed in a cylindrical shape having a uniform thickness dimension by rubber having corrosion resistance to gas, elasticity and flexibility. In the cylindrical members 15, the partial diametrical expansion and deflection are not caused when gas normally flows toward the downstream side from the upstream side. For example, even if pulsation generated from a combustor propagates toward the main body 11, the pulsation does not propagate inside the main body 11 since the cylindrical member 15 of the outflow port 13 deflects, so that a measurement error can be reduced. Even if the pulsation propagates toward the main body 11 from the upstream side of the flowmeter 10, the cylindrical member 15 of the inflow port 12 damps the pulsation while partially diametrically expanding toward the tip side from the base end side, so that a measurement error is not caused.

摘要翻译：要解决的问题：通过设置从流入口和流出口中的一个向下游侧延伸的柔性圆柱形构件来减少脉动流的影响来精确地测量流量。解决方案：在流量计10中，圆柱形构件15安装在设置在主体11中的流入口12和流出口13中的下游侧。这些圆柱形构件15通过橡胶形成为具有均匀厚度尺寸的圆柱形对气体具有耐腐蚀性，弹性和柔韧性。在圆柱形构件15中，当气体正常地从上游侧流向下游侧时，不会引起部分直径膨胀和偏转。例如，即使从燃烧器产生的脉动向主体11传播，由于流出口13的筒状部件15偏转，脉动也不会在主体11的内部传播，所以能够降低测定误差。即使脉动从流量计10的上游侧向主体11传播，流入口12的筒状部件15从基端朝向顶端侧部分地径向膨胀而阻止脉动，使得测量误差不是造成的。

摘要： PROBLEM TO BE SOLVED: To provide a decision device and method capable of preventing an increase in burden on an operation unit of microcomputer or the like when determining whether a gas apparatus is used.
SOLUTION: In the gas meter 40, a regular measurement mode executing part 43a measures flow rate once every approx. 2 seconds, while a simplified measurement mode executing part 43b measures variation in gas flow rate of not less than the prescribed value at intervals of once every approx. 0.1 seconds so as to infill the measurement intervals of once every approx. 2 seconds. Thus a high-speed measurement mode executing part 43c determines whether gas fittings 10 with governors, etc. are used from frequency and amplitude of the waveform obtained by acquiring electric signal from a pressure sensor 42, when variation in gas flow rate of not less than the prescribed value has been measured.

SOLUTION: The gas is made to flow to a master-and-slave type differential pressure regulator 1 from a propane gas cylinder 10 through a main regulator 20. A master regulator 11 of the master-and-slave type differential regulator 1 supplies the gas to the apartment house 40 side from the gas supply pipe 30. A slave regulator 12 is connected to a bypass gas passage 2 continuous to the gas supply pipe 30, bypassing the master regulator 11. A microcomputer gas meter 3 is provided for the bypass gas passage 2. The gas pressure is sampled at a high speed by a pressure sensor of the microcomputer gas meter 3 so as to detect a state of the use of a gas appliance 50. A flow rate of the gas is detected by the flow sensor of the microcomputer gas meter 3. When the gas appliance 50 is in the state of the use and a flow rate can not be detected for a prescribed time, fault alarm processing is performed and the call is given to the processing center.
