Device for measuring the speed of discharge of a fluid temperature high, in particular in a borehole petrolier or geothermal

摘要

The invention relates to a device for measuring the speed of discharge of a fluid temperature high, comprising a casing 3 and a shaft 2 provided with a blade 1 rotating in a conduit for passage of the fluid 4 in the interior of the casing. / p & & p & the problem has solve is to allow a precise temperature high. / p & & p & the device is characterizes in that a control rotor 6 comprising the control frames peripheral devices 5 is fixed on the shaft 2, a transducer has the following 7 sensitive to the eddy currents being fixed in the casing 3 to be controlled by the reinforcements 5. / p & & p & the invention is particularly applicable to the measurements carried in the drill-holes petroleum and geothermal.
