摘要： PROBLEM TO BE SOLVED: To provide a water meter system capable of making an overall length shorter than that of a water meter system provided with a conventional water-stop part. SOLUTION: By the water meter system 100 of this form of implementation, since a movable tube body 30A functions as a water-stop part when the movable tube body 30A is arranged at a water-stop position, service water does not flow inside the movable tube body 30A from both the upstream side and the downstream side from the water meter 20A. It is thereby possible to remove the water meter 20A without causing leakage of service water from an intermediate metal fixture 10A. Since the movable tube body 30A functioning as a water-stop part is arranged inside a meter reception part 11A, an overall length is shortened in comparison with a conventional water meter system in which a water-stop part, a meter reception part, and a water pipe are arranged in a lateral row in the direction of connection.

摘要翻译：要解决的问题：提供一种能够使整体长度短于具有常规止水部件的水表系统的水表系统的水表系统。解决方案：通过这种实现形式的水表系统100，由于当可动管体30A布置在止水位置时，可移动管体30A用作止水部分，所以服务水不流动从水表20A的上游侧和下游侧的可动管体30A的内部。从而可以从水中心金属固定装置10A排出水而不会使服务水泄漏。由于用作止水部的可动管体30A配置在计量接收部11A的内部，因此与以往的水表系统相比，总体长度缩短，其中，在水位检测系统中，将停水部，仪表接收部和水管沿连接方向排列成横排。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide a water meter system capable of making attachment and removal operations of water meters more efficient than before. SOLUTION: By this form of implementation, since it is possible to simultaneously open and close both end part channels 12 and 13 of upstream-side and downstream-side of a water meter 20A by the one operation of moving a movable member 30A between first and second positions, it is possible to perform attachment and removal operations of the water meter 20A more efficiently than before. Since the movable member 30A functions as a water-stop part when the movable member 30A is arranged at a water-stop position to prevent service water from flowing inside the movable member 30A from both the upstream side and the downstream side from the water meter 20A, the discharge of service water from an intermediate metal fixture 10A is prevented after the removal of the water meter 20A.

摘要翻译：要解决的问题：提供能够使水表的附着和拆卸操作比以前更有效的水表系统。解决方案：通过这种实施方式，由于可以通过移动可移动部件30A的一个操作来同时打开和关闭水表20A的上游侧和下游侧的两个端部通道12和13 在第一和第二位置之间，可以比以前更有效地执行水表20A的附接和移除操作。由于可移动部件30A在可动部件30A配置在停水位置时起到止水部的作用，从而能够防止维护水从水表20A的上游侧和下游侧向可动部件30A内流动在去除水表20A之后，防止来自中间金属固定装置10A的使用水的排放。版权所有（C）2007，JPO＆INPIT

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic flowmeter having high reliability and capable of improving accuracy in measurement.
SOLUTION: In this ultrasonic flowmeter 10, as a sensor storing thin part 26 is raised from an end part wall 14, the sensor storing thin part 26 is separated from the end part wall 14, and a thickness dimension of the sensor storing thin part 26 can be easily controlled. Thus the accuracy in thickness dimension of a thin bottom wall 25 with which a vibrational face 36 of an ultrasonic sensor 30 is closely kept into contact, can be improved. As the thin bottom wall 25 is thinned in comparison with the whole end part wall 14, a distance from the vibration face 36 of the ultrasonic sensor 30 to the liquid can be shortened in comparison with a conventional one where the ultrasonic sensor is mounted on an outer face of a pipe of approximately uniform thickness through a bracket, the attenuation of ultrasonic wave can be reduced, and the measuring accuracy can be improved.

摘要： PROBLEM TO BE SOLVED: To improve a flow rate measurement precision by reducing the detection errors of the zero cross point of reception waves by 1.5 reciprocating noise entering a transducer at a reception side by 1.5 reciprocation between facing transducers after reflection on the transducer two times. SOLUTION: The transducer at the transmission side is arranged on an extension line at a left side in a figure in a center axis X-X in the transducer 18 at a reception side. Ultrasonic pulses from the transducer at the unillustrated transmission side enter a reflection surface 7b made of a conical inclination surface in front of an acoustic matching layer 7A in the transducer 18 for reflection as shown by arrows A', B' when entering as shown by arrows A, B, and change the directions deviating from the center axis X-X. Therefore the reflection waves A', B' do not enter the opposing transmission side transducer, and do not become 1.5 reciprocating noise. Ultrasonic waves entering as shown in arrows C, D change the direction with a larger angle, become directions C', D', and do not become 1.5 reciprocating noise. COPYRIGHT: (C)2004,JPO

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic flowmeter free from enclosure noise. SOLUTION: In this ultrasonic flowmeter 10, a measurement body 30 is divided into a first body constituent 61 including one ultrasonic sensor 50, and a second body constituent 62 including the other ultrasonic sensor 50, with the first and second body constituents 61 and 62 fixed in and combinedly held by outer sleeves 11, respectively. Since a gap G1 for ultrasonic wave transmission prevention is provided between combining surfaces of the first and second body constituents 61 and 62, the enclosure noise propagating through a pipe wall of a measurement pipe 31 is suppressed or eliminated. This allows the prevention of deterioration in measurement accuracy owing to the enclosure noise. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide a flowmeter for stably measuring a standard flow rate, etc. and a method of measuring a flow rate. SOLUTION: An ultrasonic flowmeter 10 measures a flow velocity V and temperature T1 of a gas in a measuring tube 13 by using first and second ultrasonic transmitter-receivers 14 and 15 while measuring hydrostatic pressure P1 of the gas in the measuring tube 13 by using a static pressure meter 17. A dynamic pressure P2 of the gas is calculated from the flow velocity V while a total pressure P3 is calculated by using the sum of the hydrostatic pressure P1 and the dynamic pressure P2. By using the measured or calculated actual total pressure P3, actual temperature T1, and actual total pressure P3, and a relational expression based on the Boyle-Charle's law, the actual flow velocity V is output by calculating a standard unit flow rate Qx and the standard flow rate Q. The flow rate Qx is of the gas flowing through a unit area in the measuring tube 13 at previously determined standard temperature T0 and standard total pressure P0. The flow rate Q is found by multiplying the flow rate Qx by the inside cross-section of the measuring tube 13. COPYRIGHT: (C)2011,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic flowmeter improved in measuring precision, compared with one in the prior art, and a manufacturing method therefor.
SOLUTION: In this ultrasonic flowmeter 10 of the present invention, a multicylindrical part is constituted of the first cylindrical body 12A, the second cylindrical body 13A, and a multiplex pipe 30 to extend a propagation distance of a casing propagation wave, and the casing propagation wave propagated through a meter housing 11 is received by an ultrasonic sensor 20 in a reception side, with a time lag from an ultrasonic wave (fluid propagation wave) propagated through a fluid. The casing propagation wave may be attenuated until it reaches the ultrasonic sensor 20 in the reception side. In addition, a sensor-to-sensor distance L1 is never fluctuated, because the first housing 12 is coupled to the second housing 13 by the multiplex pipe 30. A propagation time of the fluid propagation wave is thereby measured accurately to increase the measuring precision of a flow velocity of the fluid (for example, hydrogen gas and water), or a flow rate thereof, compared with one in the prior art.

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic water meter which reduces space for being attached to a water pipe with ensuring propagating distance of ultrasonic waves.
SOLUTION: The ultrasonic water meter 60 is provided with a pair of ultrasonic transmitters/receivers 76, 76 at both tips of a nearly U-shaped curving water conduit 68. Ultrasonic waves transmitted/received between the two ultrasonic transmitters/receivers 76, 76 are allowed to transmit through tap water flowing through the curving water conduit 68, reducing space for being attached to a water pipe with ensuring propagating distance of ultrasonic waves. The curving water conduit 68 is formed in an angular U-shape in which lower ends of vertical linear sections 69, 69 are connected with a horizontal linear section 70, requiring less number of reflections of ultrasonic waves on the inner surface of the curving water conduit 68 compared to the one formed in a nearly U-shape with roundness.

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic flowmeter capable of measuring the flow velocity and/or quantity of flow of a plurality of liquids of different temperatures in an installation space more compact than before and to provide a hot water supply system.
SOLUTION: The ultrasonic flowmeter 10 is provided with a first measuring part provided for a first channel through which a liquid flows; a second measuring part provided for a second channel through which a liquid different from the liquid flowing through the first channel flows; a pair of ultrasonic transmitter/receivers, each being provided for the first measuring part and for the second measuring part and separately arranged on the upstream side and on the downstream side of the channels for transmitting and receiving ultrasonic waves in both directions of the forward direction along the flow of the liquids and the backward direction opposite to that of the flow; an operation part for computing the difference in the arrival times of ultrasonic waves in the forward direction and the backward direction between the pair of ultrasonic transmitter/receivers; and a switching means for alternately switching between the first measuring part and the second measuring part to connect to the operation part. Since it is possible to compute both measurement values (the velocity and quantity of flow and temperatures) on water at ordinary temperatures and measurement values on heated water formed by heating the water at normal temperatures in a common single arithmetic processing part 18 by the ultrasonic flowmeter 10, the size of the ultrasonic flowmeter 10 can be made smaller than that of a simple combination of two conventional vane-wheel type flowmeters and suppress its installation space smaller than before.
