摘要：#$%^&*AU2017204557A120170727.pdf##### ABSTRACT In accordance withone embodiment, a controller in a fluid delivery system 5 controls magnitudes of

pressure in a first volume and a second volume. The first volume is of a known magnitude.The second volume is of an unknown magnitude and varies. The controller estimates atemperature of gas in the first volume and a temperature of gas in the second volumebased on measurements of pressure in the first volume and measurements of pressure inthe second volume. The controller then calculates a 10 magnitude of the second volumebased on measured pressures of the gases and estimated temperatures of gases in thefirst volume and the second volume. At multiple different times during a delivery phase,the controller temporarily discontinues application of the pressure to the chamber tocalculate how much of the fluid in the chamber has been pumped to the target recipient.
