The online flow meter is a turbine flow meter connected in the middle position of the instrument string. When used in combination with a full-bore flow meter, it can measure the production profile in both the tubing and casing in a single trip downhole. Especially in horizontal wells, when the full-bore flow meter is damaged by wellbore cuttings, the online flow meter can serve as a backup flow meter.
