Claim 14:
15. A computer program product for use on a computer system for precision liquid delivery, the computer program product comprising a tangible, non-transient computer usable medium having computer readable program code thereon, the computer readable program code comprising:
program code for providing an input power to a tightly load-coupled pneumatic driver (a “TLCP driver”) to produce a gas drive pressure that moves gas into a gas reservoir, the gas reservoir being pneumatically coupled with a fluid path that receives a fluid drive pressure from the gas drive pressure at an interface;
program code for causing one or more pressure sensors to measure pressure in the gas reservoir and the fluid reservoir (a) prior to pneumatically coupling the gas reservoir and the fluid reservoir, and (b) after pneumatically coupling the gas reservoir and the fluid reservoir; and
program code for computing a volume of unknown liquid in the fluid reservoir.
