Abstract
A flowmeter detector for determining the flow volume of a fluid medium that includes a measuring line having first and second ends and a fluid medium entry and exit ports adjacent the fist and second ends and fluid medium flowing between the entry and exit ports is disclosed. An acoustic transducer is located at each end of the measuring line and each acoustic transducer has an overall dimension less than the cross-section diameter of the measuring line. The acoustic transducers are first operated to simultaneously transmit pulsed acoustic energy into the measuring line. The transducers are subsequently operated to receive the acoustic energy propagated through the measuring line. The flow volume is determined by evaluating the difference in the travel times of the pulsed acoustic energy propagated through the measuring line.
