Abstract
A system and method provides a flow measurement system for steady-state and transient flow. A housing contains a sleeve such that the sleeve is isolated from external mechanical Strains along the sleeve caused by flow pressure changes through the flow element are detected and related to fluid flow rate.
Claims44
A system for measuring a fluid flow comprising:
- a housing adapted to be inserted in a flowline;
- a sleeve adapted to sealably fit into said housing such that a predetermined gap exists between said sleeve and said housing and wherein said sleeve is substantially isolated from mechanical loads on said housing;
- ad
- a flow measuring element disposed in the sleeve such that the flow element generates a pressure difference across said flow element related to a flow rate of the fluid flow therethrough;
- and
- a first strain sensor attached to the sleeve upstream of the flow measuring element and generating a first signal related thereto, and a second strain sensor attached to the sleeve downstream of the flow measuring element and generating a second signal related thereto, wherein a difference between the first strain sensor signal and the second strain sensor signal is related to a flow rate of the fluid inside the sleeve.
