Droplet separator is designed for sampling the liquid phase at the wellhead of gas wells, on plumes and assessing its quantity in the gas. The droplet separator is a small-sized separator of vortex type, in which the process of separation of liquid phase from the gas flow takes place. The sampling medium is natural and associated gas from wells. The amount of mechanical impurities in the measured medium must not result in total abrasion and corrosion wear of more than 0.1 mm per year.
