A non-invasive online system for continuous measurements of phase levels in a converter or pyrometallurgical furnace in smelting and conversion processes, consisting in a electrical signal generator, transducers that convert said electrical signals in mechanical waves placed on the outer end of air blowing tuyeres, coupling means between said system and the shell of the converter, transducers placed in the direction of the axis orthogonal to the phases plane for applying mechanical waves that travel in a transversal direction into the converter, a mechanical waves sensor placed around the external wall of the shell of the converter that receives the reflected signal, a crystal local oscillator, means for the preamplification of the signal, an analogous/digital interface, a means for data acquisition, a means for processing the signals so as to determine the power of the reflected signal and the propagation time of the signal between the moment it is emitted by the transducer and the moment in which the reflected signals are received by the sensor, a memory means to store the continuous values of the phase levels and a visualisation means for displaying the continuous values of the phase levels.
- A non-invasive online phase level continuous measurement system in a converter or pyrometallurgical furnace, well defined because it consists in:
- A continuous measurement system of claim 1, well defined because the phases have different densities and consist of metal bath, slag and gases.
- A continuous measurement system of claim 1, well defined because the mechanical waves are sonic waves.
- A continuous measurement system of claim 1, well defined because the mechanical waves are ultrasonic waves.
- A continuous measurement system of claim 1, well defined because the mechanical waves are infrasonic waves.
- A continuous measurement system of any one of the preceeding claims, well defined because said pyrometallurgical converter is a Teniente Converter (CT).
- A continuous measurement system of claim 1, well defined because a sensor, at least one, is installed immediately beside each transducer, at least one.
- A continuous measurement system of claim 1, well defined because a sensor, at least one, is integrated to the respective transducer.
- A continuous measurement system of claim 1, well defined because the determination of the continuous phase levels is related to the position of the transducers.
