ULTRASONIC CLAMP-ON MULTIPHASE FLOWMETER |
摘要 |
A multiphase flowmeter for determining at least one characteristic of a first phase flowing in a pipe with at least a second phase being also present in the pipe is disclosed. The multiphase flowmeter includes a processor configured to determine the at least one characteristic of the first phase, a first transducer configured to emit a first pulse signal into the first phase at a first incident angle with respect to a straight line that is perpendicular to an interior pipe wall; the first pulse signal is in an ultrasonic range and is configured to be coupled to an exterior pipe wall; and the absolute value of the first incident angle in the first phase is configured to be at least 10 degrees and at most 80 degrees and a second transducer configured to emit a second pulse signal into the first phase at a substantially normal incidence. |
