  • Fluid meter construction
    Patent number: 5728948
    Abstract: A fluid meter has a central cylindrical section in which time-of-flight ultrasonic measurements can be made between acoustic transducers disposed in spaced apart enlarged end sections. The central section has a smaller diameter than do the end sections. Transitional regions join the end sections to the central cylindrical section. The transducers are located at least in part in the transitional regions. The transitional regions in the intermediate central section are generally shaped such that in combination with the shape and location of the transducers, pressure drops along the central section along with back-reflections of acoustic pulses from the transitional regions are reduced.
