摘要： PROBLEM TO BE SOLVED: To achieve accurate dilution of an exhaust gas by a method wherein a part of an exhaust gas is extracted at a fixed ratio with respect to a total flow rate to be diluted and then, the speed of the exhaust gas is intermittently increased up to near a sound speed to adjust an exhaust gas speed distribution containing a drift or the like. SOLUTION: A diesel engine 200 is driven to introduce an exhaust gas discharged to an exhaust gas splitter 10 through an exhaust pipe 205. In the exhaust gas splitter 10, a clearance having an axially symmetrical cross section to a spindle is equally divided in the circumferential direction by a tubular member. The exhaust gas adjusted to an axially symmetric flow runs to a gap of an expanded part 14 to make a circular flow. The flow of the exhaust gas in the expanded part 14 is always turned to a circumferentially uniform flow, reaching a branched pipe part 20. The clearance of the branch pipe part 20 is evenly divided circumferentially by the tubular part in any radial position. Thus, even when a pulsating engine exhaust gas is introduced into the exhaust gas splitter 10, the pulsating flow can be evenly divided and extracted.

摘要： PURPOSE:To enable a flowmeter to make continuous measurement and, at the same time, to eliminate measurement error from the flowmeter even when a temperature change occurs. CONSTITUTION:The title flowmeter is provided with three fluid containers 11, 12, and 13 which are filled with a fluid to be measured and have the same cross section, a differential pressure gauge AP which can detects the fluid head in each container, and switching means V1-V6 which selectively connect the containers to fluid inlets or outlets and, at the same time, connect any two of the containers to the gauge DELTAP. While the fluid is discharged to the fluid outlet from the first container after the container is filled up with the fluid, the fluid head in the first container is measured with the gauge P by using the fluid in the second container which has been filled up with the fluid as a reference. In addition, the third container is filled up with the fluid during the measurement. Thus the three kinds of operations of measuring process, filling process, and referring process are repeated by successively switching the first, second, and third containers to each other.
