Abstract
A method and device for pumping a petroleum fluid passing through a pipe and having a quantity of gas and a quantity of liquid. The quantities of gas and liquid are measured to determine the weight of the fluid in a section of the pipe and, depending upon the relative quantities of the gas and liquid measured, an additional quantity of gas or liquid is added prior to the fluid containing the additional quantity being pumped. After the fluid has been pumped, the quantity of gas or liquid serving as the additional added quantity is sampled.
