Abstract
A method of detecting a boundary of fluid flowing through a pipe, the method comprising receiving a time-varying signal corresponding to changes in content flowing through the pipe analysing said signal in the time domain, said analysing including processing said signal to produce a processed signal, searching said processed signal for a predetermined feature so as to identify a location of said boundary if said predetermined feature is found.
Claims64
A method of detecting a boundary of fluid flowing through a pipe, the method comprising:
- receiving a time-varying signal corresponding to changes in content flowing through the pipe;
- and
- analysing said time-varying signal in the time domain, said analysing including processing said time-varying signal to produce a processed signal, searching said processed signal for a predetermined feature so as to identify a location of a boundary if said predetermined feature is found.
Apparatus for detecting a boundary of fluid flowing through a pipe, the apparatus comprising:
- a sensor for receiving a time-varying signal corresponding to changes in content flowing through the pipe;
- and
- a processor for analysing said time-varying signal in the time domain, said processor being configured to produce a processed signal, to search said processed signal for a predetermined feature so as to identify a location of said boundary if said predetermined feature is found.
