TLDR
In this article, a linear spark was used as the source of the ultrasound pulse and two quartz crystals downstream and upstream of the source were used as receivers to measure the flow properties at the intake and exhaust of an engine.Abstract:
A new ultrasonic meter is described which uses a linear spark as the source of the ultrasound pulse. Two quartz crystals downstream and upstream of the source act as receivers. The time taken by the pulse to reach the receivers is determined by the velocity and temperature of the gases. The flow properties at the intake and exhaust of an engine are measured using this meter.read more
