Abstract

A method of supervising and controlling an E-line position in a centrifugal separator and a centrifugal separator include the E-line positon being continuously calculated based on inter alia, monitored density of light and heavy liquid phases, and monitored pressure at outlet side of light and/or heavy liquid outlet passages. First and/or second valves are controlled to control the E-line position, based on the supervised E-line position.
