Abstract
A disclosed dynamic receiver includes a housing defining a receiver chamber and having a first end cap at one end of the housing and a second end cap at an opposing end of the housing, a flexure membrane arranged within the receiver chamber and providing a membrane wall having a first end that is closed and arranged adjacent a fluid inlet into the receiver chamber and a second end that is open and secured to an inner wall of the receiver chamber, and a piston assembly movably arranged in the receiver chamber and including a piston head and a piston rod extending axially from the piston head, wherein, as filtrate from a test fluid enters the fluid inlet, the filtrate acts on the flexure membrane such that hydraulic fluid disposed within the membrane cavity is displaced and thereby moves the piston assembly axially within the receiver chamber.
