Abstract
A transmitting and/or receiving head for a sonic flowmeter measuring moving fluids by the runtime method, with an enclosure, an ultrasonic transducer transmitting ultrasound signals into and/or receiving ultrasound signals from the moving fluid and with an ultrasound waveguide by way of which the ultrasound signals are injected into and/or extracted from the moving fluid. The transmitting and/or receiving head is particularly well suited to utilization in a sonic flowmeter for very hot fluids, especially hot gases, by virtue of the fact that it employs an ultrasound waveguide in the form of an elongated sonic funnel offering high thermal conduction resistance.
