  • Transducer for arranging in a fluid, particularly for the measurement of the flow-velocity of a fluid in a pipe, by transmitting/receiving sonic pulses
    Patent number: 4945276
    Abstract: A transducer for arranging in a fluid particularly for the measurement of the flow velocity of a fluid in a pipe by transmitting/receiving sonic pulses, is designed as a cupshaped metal body (5), whose base (2) as membrane (3) is assigned an electrode (4) on its inside, which is sealed off against the environment i.e. against the fluid, and whose cup wall is designed with an annulus (6) filled with a powerful damping material (8), for example epoxy, rubber or epoxy mixed with metal particles.

  • Ultrasonic flow meter using obliquely directed transducers
    Patent number: 4914959
    Abstract: A transducer system and method is provided for ultrasonic measurement of the flow velocity of a fluid in a pipe. Two transducers are mounted on opposite sides of a pipe, the second transducer being downstream from the first. The two transducers alternately transmit and receive ultrasonic pulses along respective center axes which are deviated upstream from an imaginary line connecting the transducers.
