Abstract
A system for recovering vapor emerging from a tank to which liquid is being delivered wherein a vapor pump sucks vapor from the tank with a volumetric flow that is equal to the volumetric flow of the liquid as modified so as to compensate for the change in volume of the emerging vapor caused by its proximity to the entering liquid, and apparatus for measuring the actual vapor flow and adjusting the volumetric flow of the vapor pump so that it is equal to the flow required for ideal compensation.
