Abstract
The present invention provides a new method and apparatus for receiving signals containing information about a plurality of velocity profiles of a flow in a pipe and about a pressure gradient of the flow over a length of the pipe; and determining information about an injection of a chemical into the flow in the pipe based at least partly on the information contained in the signals.
Claims41
Apparatus, including a signal processor, comprising:
- one or more modules configured to:
- receive signals containing information about a plurality of velocity profiles of a flow in a pipe and about a pressure gradient of the flow over a length of the pipe;
- and
- determine information about an injection of a chemical into the flow in the pipe based at least partly on the information contained in the signals.
Apparatus, including a system, comprising:
- a data gathering module configured to respond to a flow in a pipe and provide signals containing information about a plurality of velocity profiles of the flow in the pipe and about a pressure gradient of the flow over a length of the pipe;
- and
- a signal processor comprising one or more modules configured to receive the signals containing information about the plurality of velocity profiles of the flow in the pipe and about the pressure gradient of the flow over the length of the pipe, and determine information about an injection of a chemical into the flow in the pipe based at least partly on the information contained in the signals.
A method comprising:
- receiving signals containing information about a plurality of velocity profiles of a flow in a pipe and about a pressure gradient of the flow over a length of the pipe;
- and
- determining information about an injection of a chemical into the flow in the pipe based at least partly on the information contained in the signals.
Apparatus, including a computer-readable storage medium, having computer-executable components for implementing a method comprising:
- receiving signals containing information about a plurality of velocity profiles of a flow in a pipe and about a pressure gradient of the flow over a length of the pipe;
- and determining information about an injection of a chemical into the flow in the pipe based at least partly on the information contained in the signals, when executed on a signal processor running on a computer device.
Apparatus comprising:
- means for receiving signals containing information about a plurality of velocity profiles of a flow in a pipe and about a pressure gradient of the flow over a length of the pipe;
- and
- means for determining information about an injection of a chemical into the flow in the pipe based at least partly on the information contained in the signals.
- Alternative Embodiment
