Abstract: A flowmeter for detecting fluid flow rates in a pipe includes a tube having a channel disposed in the pipe through which fluid in the pipe flows. The flowmeter includes an upstream transducer in contact with the pipe and positioned so plane waves generated by the upstream transducer propagates through the channel. The flowmeter includes a downstream transducer in contact with the pipe and positioned so plane waves generated by the downstream transducer propagate through the channel and are received by the upstream transducer which produces an upstream transducer signal. The downstream transducer receives the plane waves from the upstream transducer and provides a downstream transducer signal. The flowmeter includes a controller in communication with the upstream and downstream transducers which calculate fluid flow rate from the upstream transducer signal and the downstream transducer signal. A method for detecting fluid flow rates in a pipe.

Abstract: The present invention relates to a method of obtaining value from providing fabrication equipment comprising the following steps. Fabrication equipment is provided to an article producer, which equipment includes an on-line analyzer for detecting the presence of a tracer element. Raw material which contains the proprietary tracer element is then provided to the article producer. The article producer is then allowed to begin to convert the raw material to a finished article using the fabrication equipment. The raw material is analyzed for the presence of the tracer element while the fabrication equipment is operated. Appropriate action, such as charging a royalty or shutting down the fabrication equipment, is then taken in the event the tracer element is not detected.
