DEVICE FOR CHECK-UP OF MEDIUM CORROSIVITY Russian patent published in 2003 - IPC

FIELD: gas industry and designed for check-up of medium corrosivity in pipe- lines or in some production units. SUBSTANCE: the device for check-up of medium corrosivity has supply and data processing units connected to the medium corrosivity monitor having a sensitive element located in the corrosive medium and made of conducting material. The monitor is made in the form of a turned-over hollow body with a bottom accommodating in parallel with the bottom two flat inductance coils with a dielectric positioned between them, filled with chemically-resistant insulating material, and the sensitive element is fastened on the chemically- resistant material by one of its sides in parallel with the inductance coils. The monitor may be provided with a permanent magnet located in the body between the body and the inductance coil, the sensitive element may be made of foil and fastened on the chemically-resistant insulating material with the aid of a chemically thermoresistant adhesive. A thread may be made on the opposite side of the bottom along the edge of the body outer surface and a nut with a bead fastening the sensitive element on the chemically-resistant insulating material and preventing any contact of the chemically-resistant insulating material with the corrosive medium is turned on it. EFFECT: continuous monitoring of the tested corrosive medium and enhanced sensitivity of the respective measurements it time. 5 cl, 5 dwg
