  4. 3. Gap discharge transducers applied to ultrasonic flow measurement

    Författare :Kristoffer Karlsson; Per Lunde; Luleå tekniska universitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Industriell elektronik; Industrial Electronics;

    Sammanfattning : In this thesis, the potential of the gap discharge transducer is investigated as both a sound pulse emitter and a sound pulse receiver in a gas flow measurement setup. The main objective is to use the gap discharge transducer as an integral part in a gas flow measurement system developed for harsh environments. LÄS MER
