Abstract
A system, including an ultrasonic flow meter with a conduit including a conduit wall and configured to flow a fluid, an housing disposed about the conduit to define a fluid chamber about the conduit, wherein the conduit facilitates fluid flow into the fluid chamber and through the ultrasonic flow meter and a first ultrasonic transducer disposed in the fluid chamber.
Claims24
A system, comprising:
- an ultrasonic flow meter, comprising:
- a conduit comprising a conduit wall disposed about an internal passage, wherein the conduit is configured to flow a fluid through the internal passage;
- a housing disposed about the conduit to define a fluid chamber about the conduit, wherein the fluid chamber is in fluid communication with the conduit;
- and
- a first ultrasonic transducer disposed in the fluid chamber, wherein the first ultrasonic transducer is coupled to the conduit.

An apparatus, comprising:
- a chemical-injection management system of a sub-sea oil and gas extraction system, comprising:
- a flow path having an inlet and an outlet;
- and
- an ultrasonic flow meter disposed in the flow path between the inlet and the outlet, wherein the ultrasonic flow meter comprises:
- a conduit;
- a housing disposed about the conduit to define a pressurized fluid chamber about the conduit;
- and
- a first ultrasonic transducer disposed in the pressurized fluid chamber.
5 more elements
A system, comprising:
- an ultrasonic flow meter, comprising:
- a conduit surrounding a fluid flow path;
- a first ultrasonic transducer;
- a second ultrasonic transducer, wherein the first and second ultrasonic transducers are configured to measure a fluid flow along the fluid flow path;
- a static fluid chamber at least substantially isolated from the fluid flow path, wherein the first and second ultrasonic transducers are disposed in the static fluid chamber;
- and
- an acoustic damping material disposed in the static fluid chamber outside of the conduit, wherein the acoustic damping material is disposed between the first and second ultrasonic transducers.
