PURPOSE:To make it possible to establish the effective control system of geothermal steam by enabling the accurate measurement of the flow amount of a two-phase fluid, by inspecting the dilution ratio of a tracer reagent by sampling the two-phase fluid on the way of a pipeline after mixing the tracer reagent in said fluid. CONSTITUTION:The two-phase fluid consisting of steam and hot water collected from a production well 1 is supplied to electric power installation by a pipe 2. A tracer injection apparatus 3 is attached to the side wall of the production well 1 protruded from the ground surface and injects a constant amount of the tracer metered from a tank 4 by a quantitative pump 5 into the two-phase fluid injected into the production well 1 through a valve 6. The two-phase fluid in which the tracer is injected is sampled by the sampling valve 8 provided in the pipe 2 and the concn. of the tracer in the sample is measured to calculate a hot water flow amount from a predetermined formula. |
