International Classification:

G01N 29/02

US Classification:

73641, 73599, 73600, 73602

Abstract:

An apparatus for detecting and measuring gas voids in a pipe with a fluid includes a first ultrasonic transducer externally disposed on the pipe. The apparatus includes a second ultrasonic transducer externally disposed on the pipe. The apparatus includes a multiplexer, transmitter, receiver, controller and processor in communication with the first transducer and the second transducer which in combination identify a void in the pipe from ultrasonic measurements of properties of the fluid in the pipe. A method for detecting and measuring gas voids in a pipe with a fluid includes the steps of measuring properties of the fluid internal to the pipe with transmissions of ultrasonic energy from transducers externally disposed on the pipe. There is the step of identifying a void in the pipe from the properties of the fluid internal to the pipe using signals processed by processor.

International Classification:

G01F 1/66

Abstract:

An apparatus for determining fluid flow in a pipe including a transit time chordal ultrasonic meter that eliminates dependence of meter factor on Reynolds number for measuring the flow through the pipe. The meter having a bore through which the fluid flows and a plurality of cavities with transducers disposed in the cavities which produce ultrasonic pulses that pass through the fluid and define multiple chords. The fluid velocity measured by clocking the pulses' time traveling diagonally upstream and downstream between pairs of the transducers. The transducers in the cavities isolated from the fluid flow in the bore by each cavity of the cavities having a liner which separates each cavity from the bore. A method.
