Aneroid volume determining system

摘要

An aneroid volume determining system includes an airtight chamber for holding a subject whose volume is to be detected; a volume adjuster including an inflatable container for varying the pressure in the chamber; sensing equipment including a pressure transducer for sensing the pressure in the chamber in the deflated and inflated states of the container; and controlling equipment, which can calculate the volume of the subject in response to the pressure sensed in the chamber with and without the subject present in the chamber and which equipment provides control signals to the volume adjuster for automatically controlling the inflation and deflation of the inflatable container.
