When submergence occurs and water is raised up to W2, the electrodes 12, 13 are dipped in the water. Then, the electrodes 12, 13 are short circuited by the water, and the electric resistance value between both electrodes is lowered abnormally. The submergence is noticed by the abnormal lowering. The submergence warning is issued to the outside of the gas meter.

摘要： PROBLEM TO BE SOLVED: To provide a gas flowmeter capable of reducing the burden of work in adjusting and inspecting processes. SOLUTION: In this gas flowmeter 10, specific trigger is applied to the gas flowmeter 10 from the external in a state of applying a gas of specific pressure to the gas flowmeter 10 to conduct an airtight test. Then an external airtight self-inspecting program 11 of the gas flowmeter 10 is started to judge the presence of gas leakage when the pressure change is found, and the absence of gas leakage when the pressure change is not found. As the presence or absence of the gas leakage is determined by the gas flowmeter 10 itself, the worker burden can be reduced. Further as the presence or absence of the leakage is determined by utilizing a pressure sensor 16 mounted on the gas flowmeter 10, the equipment cost for the adjusting and inspecting processes can be reduced.

摘要： PROBLEM TO BE SOLVED: To provide an ultrasonic flowmeter capable of shortening the overall length of a measuring housing more than before. SOLUTION: Since the ultrasonic flowmeter 10 does not require a structure in which the sensor housing part 24 is open to the outside of the measuring housing 11 open to the outside, it is possible to eliminate the need for a cap for blocking an outside opening of the sensor housing part as before. Since it is thereby possible to provide a constitution in which both end surfaces of the measuring housing 11 are made close to proximate positions of the sensor housing part 24, it is possible to shorten the overall length of a measuring housing 11 more than before. It is therefore possible to shorten an installation space for the measuring housing 11 to be required at a midpoint in a piping 60 more than before. COPYRIGHT: (C)2008,JPO&INPIT

摘要： PROBLEM TO BE SOLVED: To enhance accuracy of flow measurement while reducing the size of a flowmeter.
SOLUTION: In a sound wave flowmeter, a fluid flows in the horizontal direction in flow paths 1a, 1b, and 1c of a measuring tube 30 as shown in Fig. (b). An ultrasonic wave is caused to propagate through the fluid along a straight line 6 inclined at an angle θ from an axis line Xa - Xa of the flow path 1a to calculate a flow speed based on forward propagation time in the same direction as a flow and reverse propagation time in the reverse direction, thereby operating a flow volume. As to the flow paths, the three flow paths 1a, 1b, and 1c are provided around the straight line 6 so as to be shifted from each other by 120° as shown in Figs. (c) and (d). Each flow path is equipped with a rectangular cross-section of height H and width W.
