The gap discharge transducer as a sound pulse emitter in an ultrasonic gas flow meter
Kristoffer Karlsson, Jerker Delsing · Epubl LTU · 2013
In this paper the gap discharge transducer is used as a sound pulse emitter in an ultrasonic flow measurement setup to determine its capabilities to measure a gas flow. An industrial fan and a 3 m long pipe with diameter 62 cm was used to create a flow scenario. The gap discharge transducer was placed between two standard piezoelectric receivers to mimic an ultrasonic flow meter setup. A hot-wire anemometer was used as reference. The gap discharge transducer shows good potential as a sound pulse emitter in a flow measurement setup if more care is taken in aligning the system
