An apparatus for measuring fluid flow includes a housing, a first ultrasonic transducer, and a fluid flow path. The housing defines a smooth bore and a first cavity. The first cavity is separated from a fluid that flows through the smooth bore. The first ultrasonic transducer is disposed within the first cavity and transmits an ultrasonic pulse through the fluid. The fluid flow path extends from an upstream intake through the cavity.

Smooth bore, chordal transit-time ultrasonic meter and method

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 for determining fluid flow in a pipe.

An apparatus that includes a chemical injection management system. The chemical injection management system may include an interface configured to couple the chemical injection management system to a mineral extraction system. In addition, the chemical injection management system may include an ultrasonic flow meter.

A flow element for an ultrasonic flowmeter having a plurality of transducers for analyzing fluid flow in a pipe. The flow element includes a housing having a bore with an internal diameter and a surface through which fluid flows and a plurality of cavities each of which has an opening in the surface. Each of the cavities has one of the plurality of transducers disposed in it. The flow element includes a liner that covers the openings of the cavities which prevents fluid flowing through the bore from entering the cavities.

An apparatus for analyzing fluid flow in a pipe includes an ultrasonic flowmeter having a plurality of transducers. The apparatus includes a flow element having a completely smooth bore through which the fluid flows, and a plurality of cavities, each of the cavities has one of the plurality of transducers disposed in it and which is in communication with the fluid flowing through the bore.

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.
