Abstract
An apparatus for tracer based flow measurement may include a tracer chamber for installation in and/or on a production tubing, wherein the tracer chamber is for holding tracer and is arranged to be linked, in use, to the pressure in an annulus about the production tubing. The tracer chamber may include an outlet for fluid communication between the tracer chamber and the fluid within the production tubing, whereby tracer is released from the tracer chamber into the production tubing in accordance with a pressure differential between the annulus and the production tubing.
