Abstract
The pressurized magnetic float level indicator for recipients containing liquids at high pressure and temperature of the invention comprises a tubular body with a vertical axis which is closed at its ends and communicates at the top and bottom with a recipient containing liquid whose level is to be indicated, within which there is a float (5) provided with a magnetic element (11) designed to orientate a plurality of rotary magnetic dipoles aligned in parallel with the tubular body, the float (5) being provided with inner rings (10) and being pressurized with an evaporating mixture having a stream pressure which varies with variations in the internal temperature of the float (5) along a curve corresponding to the variation of the pressure with the temperature of the liquid contained in the recipient and in the tubular body externally to the float (5), this stream pressure within the float at least partially balancing out the pressure outside it.
