ABSTRACT:
A flow measurement having a substantially cylindrical housing with a valve element connected to an inner surface thereof. The valve is movable between an open position and a closed position in the bore. A secondary flow passageway is formed in the housing and extends along the longitudinal axis of the housing. A first end of the secondary flow passageway is in fluid communication with the bore below the valve element. A flow measuring device is located near a second end of the secondary flow passageway for measuring the rate of fluid flow therethrough. The housing is adapted to be connected at each end thereof to well tubing. The present invention provides a flow measurement mandrel that diverts the production flow the secondary flow passageway by closing a hydraulically operated flapper valve and routing the fluid or gas through the a venturi flume in the secondary flow passageway for flow measurement. After monitoring flow rate, the flapper valve is re-opened and full bore production is achieved.
