| Abstract |
The report describes the development of a device that is capable of sampling gaseous emissions from automobiles. The device samples exhaust gases at a mass rate that is proportional to the total exhaust gas mass flow rate, which is measured using an ultrasonic vortex flowmeter. The flowmeter delivers signals, which are conditioned by process control electronics, to a sample valve. Non-standard temperature and pressure conditions at both the vortex flowmeter and the sample valve are compensated for in the process control electronics. The report focuses primarily on development of the vortex flowmeter, the sample valve, and the process control electronics. These three components comprise the heart of the proportional sampling system. |
