Abstract
A method and apparatus for identifying the fluid in a vessel, such as, a storage tank or pipeline using ultrasonic techniques. The method uses a transducer to project ultrasonic energy through the vessel and a second transducer positioned opposite the first to receive the energy that has been transmitted through the vessel and fluid. The transducers are included in a circuit whose parameters are adjusted to cause the circuit to resonate with the magnitude of the adjusted parameter being related to the fluid in the vessel.
