Abstract
A system is provided for measuring flow in a pipeline which, in use, carries a stratified flow of a first liquid and a second, denser liquid. The system comprises: a section of the pipeline in which the stratified flow is uphill; a section of the pipeline in which the stratified flow is downhill; and a holdup meter on each of said pipeline sections for measuring the holdup in each section. The flow rates of the first and second liquids can be calculated from the measured holdups.
