Two phase flow meter
First Claim
1. An apparatus for determining the relative flows of a two phase flow through a pipe having a longitudinal axis, an upstream end and a downstream end, and means for providing a two phase flow to the upstream end of the pipe, comprising:
- means for substantially separating the two phase fluid flow into a dense phase and a light phase inside the pipe adjacent the upstream end;
first means for transporting the dense phase separately through a first section of the pipe to a second section of the pipe downstream of the first section;
second means for transporting the light phase separately through the first section of the pipe to the second section of the pipe downstream of the first section;
means for thoroughly mixing the dense phase and the light phase in the second section of the pipe; and
four pressure measurement devices connected to at least four different points within said pipe to obtain four different pressure measurements which can be used to determine the rate of flow of each of the dense phase and light phase through the sections of the pipe.

Abstract
An apparatus for determining the relative flows of a two phase flow using differential pressure to obtain mass flow having a bend portion for concentrating the dense phase toward an outside of the bend; a perforated plate downstream of the bend for passing the portion of the light phase; a nozzle for channelling the portion of the flow having high density phase toward the center of a venturi throat which is positioned downstream of the perforated plate; and four pressure sensors strategically located for measuring pressure differences at various points in the flow meter.
