Abstract
The invention pertains to a measuring system for the conductivity of supercritical geothermal fluid, featuring a reaction control unit with a reaction vessel lined with corundum ceramic and containing a stirrer, a pressure control unit including a booster pump connected to Ar gas and an air compressor, a flow control unit with a flowmeter, and a temperature control unit comprising a heating furnace with thermocouples both inside and outside the reaction chamber. An electrical signal monitoring unit with electrodes fitted through a corundum capillary into the ceramic lining measures current and voltage. The invention also details a method for measuring conductivity, highlighting how water-rock interactions in supercritical geothermal fluids affect conductivity changes.
