Abstract: An osmometer of the type having an osmotic membrane rigidly fitted to a cell having an inner space filled with a reference solvent is disclosed. The outer surface of the membrane is adapted to be in contact with the liquid solution whose osmotic pressure is to be measured. The inner surface of the membrane is in contact with the solvent. A pressure transducer membrane having two sides is positioned with one side in contact with the solvent so as to respond to the osmotic pressure developed across the osmotic membrane. Means are provided for transmitting to each side of the transducer membrane any change of mechanical and hydraulic pressure that may occur at the osmotic membrane whereby the transducer membrane responds only to the osmotic pressure. In one embodiment means are also provided for balancing the osmotic pressure with a hydraulic pressure.

Abstract: A pressure-measuring system including a pressure-responsive membrane formed by the interface between two immiscible fluids bounded by the edge of an orifice in a vessel. One of the fluids is a liquid. Means are provided for detecting the position of the membrane in response to a given pressure.
