ABSTRACT:
A flow meter including a variable area obstruction which is mounted in a conduit. Inputs to a differential pressure transducer are positioned in the conduit on opposite sides of the obstruction to measure fluid pressure differential across the obstruction. In one embodiment, a sleeve is secured within the conduit thereof substantially separated from the conduit so as to prevent fluid condensation on the sleeve, and to create a dead end pocket between the conduit and the sleeve for collecting liquids from the conduit end preventing them from contacting the obstruction. The variable area obstruction comprises an elastic membrane that includes first, second and third leaves which extend into the flow stream and are compliant to fluid flow so that an increase in flow rate increases the deflection of the leaves and increases the through flow area through the obstruction. The first leaf is secured at a fixed end adjacent a first portion of the interior surface of the conduit and extends in a first direction to a free end preferably positioned adjacent a second portion of the interior surface of the conduit opposite the first portion. The second and third leaves are located adjacent opposite sides of the first leaf and extend from their fixed ends toward their free ends in directions which are generally opposite to the first direction.
