THE GAP DISCHARGE TRANSDUCER AS A SOUND PULSE EMITTER IN AN ULTRASONIC GAS FLOW METER

Kristoffer Karlsson, Jerker Delsing

Abstract

Measurements of the flow of gases and liquids are being performed routinely everywhere in the world. Be it air in a ventilation or gasoline trough a gas pump, flow measurements are an integral part of society. For most flow scenarios there are at least a couple of solutions how to perform the measurement with one or two of them being more advantageous depending on the situation. For example in some liquid flow measurements ultrasonic transducers are used to determine the flow through the time-of-flight method and in gas flows a venturi pipe might be used that determines the flow through differential pressure.
