Abstract
Official abstract text for this publication.
A flow element for an ultrasonic flowmeter having a plurality of transducers for analyzing fluid flow in a pipe. The flow element includes a housing having a bore with an internal diameter and a surface through which fluid flows and a plurality of cavities each of which has an opening in the surface. Each of the cavities has one of the plurality of transducers disposed in it. The flow element includes a liner that covers the openings of the cavities which prevents fluid flowing through the bore from entering the cavities.
First claim
Opening claim text (preview).
1 . An apparatus for determining fluid flow in a pipe comprising: a transit time chordal ultrasonic meter that eliminates dependence of meter factor on Reynolds number for measuring the flow through the pipe, the meter having a plurality of cavities with transducers disposed in the cavities which produce ultrasonic pulses that pass through the fluid and define multiple chords, the fluid velocity measured by clocking the pulses' time traveling diagonally upstream and downstream between pairs of the transducers. 2 . The apparatus of claim 1 wherein the cavities are separate, distinct and apart from the fluid in the pipe, and the cavities experiencing no significant pressure load relative to the pipe or the fluid in the pipe. 3 . The apparatus of claim 2 wherein the cavities are filled with cavity fluid having same nominal physical characteristics and a same nominal pressure as the pipe fluid in the pipe, with no interaction between the pipe fluid in the pipe and the cavity fluid in the cavity through the fluid. 4 . A method for determining fluid flow in a pipe comprising the steps of: transit time chordal ultrasonic meter that eliminates dependence of meter factor on Reynolds number for measuring the flow through the pipe, the meter having a plurality of cavities with transducers disposed in the cavities which producing with a transit time chordal ultrasonic meter that eliminates dependence of meter factor on Reynolds number for measuring the flow through the pipe ultrasonic pulses that pass through the fluid and define multiple chords, the meter having a plurality of cavities with transducers disposed in the cavities; and measuring the fluid velocity by clocking the pulses' time traveling diagonally upstream and downstream between pairs of the transducers.
