  • Single-body dual-chip Orthogonal sensing transit-time flow device
    Patent number: 6901812
    Abstract: An ultrasonic sensor having a pair of ultrasound transducers adapted to be inserted in and being able to perform at a single site of introduction into a duct. The ultrasonic sensor measures a forward ultrasonic path transit time and a second reverse ultrasonic path transit time of ultrasound signals propagating in a fluid. The arrangement being such that a comparison of the signal associated with ultrasound travel in one direction with that of the signal associated with ultrasound travel in the opposite direction enables the flow rate of the fluid in the duct to be determined. The ultrasonic sensor may utilize a reflecting surface on the duct and a reflective surface of an ultrasonic sensor end cap to provide forward and reverse ultrasonic W-shaped paths. In addition, the ultrasonic sensor may also be used to measure the temperature, viscosity, and cavitation effects of a fluid.

  • Single-body dual-chip orthogonal sensing transit-time flow device using a parabolic reflecting surface
    Patent number: 6854339
    Abstract: An ultrasonic sensor having a pair of ultrasound transducers adapted to be inserted in and being able to perform at a single site of introduction into a duct. The ultrasonic sensor measures a forward ultrasonic path transit time and a second reverse ultrasonic path transit time of ultrasound signals propagating in a fluid. The arrangement being such that a comparison of the signal associated with ultrasound travel in one direction with that of the signal associated with ultrasound travel in the opposite direction enables the flow rate of the fluid in the duct to be determined. The ultrasonic sensor may utilize a curved reflecting surface on the duct and a reflective surface of an ultrasonic sensor end cap to provide forward and reverse ultrasonic W-shaped paths.

  • Single-body dual-chip orthogonal sensing transit-time flow device using a parabolic reflecting surface
    Publication number: 20040129088
    Abstract: An ultrasonic sensor has a pair of ultrasound transducers and is adapted to be inserted in and able to perform at a single site of introduction into a duct, a manifold, or a pipe. The ultrasonic sensor measures a forward ultrasonic path transit time and a second reverse ultrasonic path transit time of ultrasound signals propagating in a fluid. The arrangement being such that a comparison of the signal associated with ultrasound travel in one direction with that of the signal associated with ultrasound travel in the opposite direction enables the flow rate of the fluid in the duct to be determined. The ultrasonic sensor may utilize a curved reflecting surface on the duct and a reflective surface of an ultrasonic sensor end cap or housing to provide forward and reverse ultrasonic W-shaped paths.
