The invention is concerned with conditioning a multi-phase stream, and in particular a gas stream with low liquid content. Specifically, the invention provides a method of conditioning a multi-phase flow of gas with entrained liquid droplets in a process stream section where a multi¬ phase measurement sensitive to the hold-up is to be made, comprising heating a surface within the section to a temperature such that droplets of liquid contacting the heated surface are subject to the Leidenfrost effect. This prevents the heated surface from being wetted by any droplets of liquid which may come into contact with it, so that liquid does not accumulate on the surface, but remains in the gas flow. As a result, accurate measurements of the overall density of the gas, and thus the amount of liquid entrained in the gas, can be made. |
