Abstract
A new high precision volume gauging system for measuring the volume of a propellant VL enclosed at a first pressure PU within a propellant tank () of a volume VT. The improved precision compared with prior art is achieved in that it comprises a high precision pressure sensor () which is comprised of a reference chamber () that is connected to the propellant tank () by a communication line (), a valve () for controlling the gas flow through the line (), and a high precision differential pressure sensor () that is arranged to record the pressure difference between the reference chamber () and the propellant tank () to which it is connected through a communication line ().
