摘要： PROBLEM TO BE SOLVED: To obtain a flowmeter by which a flow rate can be measured over a wide flow-rate range. SOLUTION: In a pipe 10, a flow passage 13 for large-flow-rate measurement and a flow passage 14, for small-flow-rate measurement, which is formed in series on the downstream side of the flow passage 13 for large-flow-rate measurement and whose cross-sectional area is smaller than that of the flow passage 13 for large-flow-rate measurement are formed. A plurality of flow-velocity sensors are installed respectively inside the flow passage 13 for large-flow-rate measurement and inside the flow passage 14 for small-flow-rate measurement. In a small-flow-rate region, a flow rate is computed on the basis of outputs of flow-velocity sensors 292 , 293 inside the flow passage 14 for small-flow-rate measurement. In a large-flow-rate region, a flow rate is computed on the basis of outputs of flow-velocity sensors 291 , 292 , 293 inside the flow passage 13 for large-flow-rate measurement.

摘要： PROBLEM TO BE SOLVED: To early and accurately detect gases leaking in soil by preparing a uniform mixed gas out of fuel gas and helium gas, and feeding the mixed gas to a main branch pipe for detecting the helium gas after the leak and diffusion thereof. SOLUTION: A flow rate ratio control circuit 11 calculates and outputs a helium gas flow rate ratio corresponding to the flow rate of LP gas, in response to a signal outputted from a gas meter 7. Also, an automatic flow rate adjuster 10 makes the adjustment of the flow rate of helium gas, so as to keep a constant flow rate ratio of LP gas to helium gas, depending on a signal outputted from the circuit 11. Thus, the flow rate ratio of LP gas to helium gas is controlled at a constant value, and both of the gases are evenly mixed with a stationary mixer 8. Furthermore, a gas mixing device mixes both gases to a constant value on the basis of the constant flow rate ratio, and a mixture of the gases is supplied to an LP gas main branch pipe 3. When the mixed gas leaks at a leak position on the main branch pipe 3 in soil, helium gas having a high diffusion rate is quickly diffused. As a result, the leak position can be early and accurately identified with a detection means on the ground.

摘要： PURPOSE:To identify from which gas species the component of combustible gas has been derived definitely without error by computing the rate of the concentration of the individual combustible gas component with the concentration value of CH4 as a reference among the measured values of the concentrations of sample gas. CONSTITUTION:Gas whose source is not known and which is leaking in the ground or on the ground surface through soil is made to be a sample gas. The concentrations of components of the combustible gas contained in the sample gas to begin with CH4, the component of inorganic gas such as CO2 and the individual component are measured. Among the measured values of the concentrations of the sample gas, the rate of the concentrations of the individual combustible gas components with the concentration value of CH4 as a reference is computed. Then, which gas species of city gas, fermentation gas or LPG is the source of the combustible gas component contained in the sample gas is identified based on the magnitudes of the concentration values of CH4, the concentration values of the combustible components other than CH4 and the concentration value of CO2 among the measured values of the concentrations and the magnitudes of the operated value of the rate of the concentrations of the individual combustible components contained in the computed sample gas.

摘要： PURPOSE:To make possible quick and exact qualitative analysis for gas constituting bubbles by completely sealing a vessel off from an outside atmosphere and filling the vessel with inert gas and releasing the inert gas in the bubbles with glass crushed. CONSTITUTION:Glass mixed with bubbles is housed in a vessel 12. Stop valves 36, 42 are opened and the atmosphere of an inside space 16 is replaced with inert gas (helium gas). The valves 36, 42 are closed, pushed by means of a glass crushing bar 24, pulled up, pushing is repeated and the glass is crushed. Because the vessel 12 is transparent, with the glass crushed fully and with all the bubbles crushed, judgement can be performed on whether the whole of the gas for qualitative analysis is released. Next, after a pipe 22 is connected to the specimen introduction inlet of a gas chromatograph GC and piping is evacuated, the valves 36, 42 are opened and the gas released from the bubbles is purged from the space 16 by means of a newly supplied helium gas for the purpose of introducing to the gas chromatograph GC and performing the qualitative analysis.
