Abstract
A measuring apparatus for measuring the volume of a contained fluid includes an exposure chamber adapted for exposure to head volume of a volume of the contained fluid. A displacement mechanism is connected to the exposure chamber such that the displacement mechanism is displaced in proportion to the amount of head volume in the contained fluid acting on the exposure chamber. A read mechanism is connected to the displacement mechanism. The read mechanism generates a signal corresponding to the amount of displacement of the displacement mechanism.

A measuring apparatus for measuring the volume of a contained fluid, the apparatus comprising the following:
- a fluid-filled exposure chamber adapted for exposure to head volume of a volume of the contained fluid;
- a displacement mechanism connected to the exposure chamber such that the displacement mechanism is displaced in proportion to the amount of head volume in the contained fluid displacing fluid within the exposure chamber, the displacement mechanism further including a guide assembly with a cylinder, a guide piston mounted for reciprocal movement in the cylinder, a first seal assembly connecting the flexible membrane to the cylinder, and a second seal assembly connecting the flexible membrane to the guide piston;
- and
- a read mechanism connected to the displacement mechanism, the read mechanism being adapted and constructed to generate a signal corresponding to the amount of displacement of the displacement mechanism.

- an expansion chamber connected to the displacement mechanism;
- and
- a read mechanism connected to the displacement mechanism, the read mechanism being adapted and constructed to generate a signal corresponding to the amount of displacement of the displacement mechanism.
A method for measuring the volume of a contained fluid, the method comprising the following steps:
- providing a fluid-filled exposure chamber adapted and constructed for exposure to head volume of a volume of a contained fluid to be measured;
- providing a displacement mechanism connected to the exposure chamber, the displacement mechanism including a cylinder, a guide piston mounted for reciprocal movement in the cylinder, a flexible membrane connected between the cylinder and the piston a first seal assembly connecting the flexible membrane to the cylinder, and a second seal assembly connecting the flexible membrane to the guide piston;
- providing a read mechanism connected to the displacement mechanism, the read mechanism being adapted and constructed to generate a signal corresponding to the amount of displacement of the displacement mechanism;
- placing the exposure chamber into a volume of contained fluid to be measured, thus displacing the displacement mechanism in proportion to the amount of head volume in the contained fluid displacing fluid within the exposure chamber and causing the read mechanism to generate a signal corresponding to the amount of displacement of the displacement mechanism;
- and
- interpreting the signal from the read mechanism to determine the volume of the contained fluid.
