DETERMINING A VOLUME OF GAS INSIDE A LIQUID SUPPLY SYSTEM

摘要

There is provided a method, comprising configuring a liquid delivery means to deliver a known volume of liquid to a liquid supply system. A first pressure of the liquid supply system after the liquid delivery means has delivered a first known volume of liquid into the liquid supply system is determined. A second pressure of the liquid supply system after the liquid delivery means has delivered a second known volume of liquid into the liquid supply system in determined. The volume of compressible gas trapped in the liquid supply system is determined from the second known volume of delivered liquid and the first and second pressures.
