    • PURPOSE: An exhaust gas measuring instrument is provided to measure the exhaust amount of several component in exhaust gas from an engine. CONSTITUTION: An exhaust gas measuring instrument has a miniature dilution tunnel (22) in which a part of exhaust gas in the exhaust pipe (15) of an engine is introduced through an extraction pipe (30) and diluted with air, a measuring means (33 and 36) which measures specific components in the exhaust gas diluted in the miniature dilution tunnel (22), a high response differential pressure type extracted gas flow meter (31 and 40) which measures the exhaust gas flow rate (Qs) in the extraction pipe (30), a high response differential pressure type bypassed gas flow meter (29 and 39) which measures the exhaust gas flow rate (Qb) in the exhaust pipe (15) and an arithmetic means (44) which calculates the flow rate dividing ratio R = Qb/Qs which is obtained by dividing the exhaust gas flow rate (Qb) by the exhaust gas flow rate (Qs). The exhaust gas measuring instrument further has a means by which the calibration coefficient (k) of the flow rate dividing ratio is obtained and ameans which obtains the calibrated flow rate dividing ratio (k.R) by multiplying the flow rate dividing ratio by the calibration coefficient. The calibration coefficient (k) can be obtained by dividing a concentration dividing ratio (Rc) by the flow rate dividing ratio (R).

    • A gas flow rate verification unit capable of enhancing reliability of gas flow rate verification. The gas flow rate verification unit has a first cutoff valve (12) that is connected to a flow rate control device (10) and to which gas is inputted, a second cutoff valve (13) for discharging the gas, a communication member (18) for allowing the first cutoff valve (12) and the second cutoff valve (13) to communicate with each other, a pressure sensor (14) for detecting the pressure of the gas supplied between the first cutoff valve (12) and the second cutoff valve (13),a temperature detector (15) for detecting the temperature of the gas supplied between the first cutoff valve (12) and the second cutoff valve (13), and a control means (16) for verifying the flow of the gas flowing in the flow control device (10), the verification being performed by using both the result of the pressure detected by the pressure sensor (14) and the result of the temperatures detected by the temperature detector (15). The volume (Vk) between the valve seat (22) of the first cutoff valve (12) and the valve seat (28) of the second cutoff valve (13) is equal to or less than the volume (Ve) between the outlet of the flow control device (10) and the valve seat (22) of the first cutoff valve (12). ® KIPO & WIPO 2009
