Periodic measurement of flow rate in production wells is essential to monitor performance of geothermal wells and reservoir. Tracer

dilution method has been introduced as a reliable, cheap and environment friendly technique to measure mass flow rate and enthalpy in

two phase geothermal systems. In this study, Sodium Fluorescein is used to measure liquid phase mass flow rate in a two phase production

line and in a single phase liquid injection line. The study includes the effect of flow regime and flowrate on the accuracy of tracer flow

test. The test results obtained for several wells in Alaşehir and Kizildere geothermal fields are confirmed with silencer-weir box method

and results of the test in a single phase liquid line is verified with orifice plate meter.
