Abstract
Un método para determinar la conductividad eléctrica de un flujo másico en un volumen blanco tridimensional (2) que incluye las etapas de colocar los electrodos (3) en una conexión de medición con el volumen blanco; alimentar voltaje alterno o corriente alterna al volumen blanco entre dos de los electrodos (3) y medir la corriente o el voltaje entre dos de los electrodos (3); determinar un modelo en espacios de estados que defina la relación entre la conductividad eléctrica, el voltaje y la corriente en el volumen blanco (2) y que también defina la evolución de la conductividad eléctrica como una función del tiempo; comparar las corrientes y/o los voltajes de acuerdo a el modelo en espacios de estados con las corrientes y/o los voltajes alimentados y los medidos; y modificar según sea necesario, el modelo en espacios de estados para disminuir las diferencias entre los resultados medidos y los calculados. De acuerdo a la presente invención, los electrodos (3) son colocados sustancialmente dentro de un plano (4); y el modelo en espacios de estados es determinado de modo que incluya el campo de flujo dependiente del tiempo del flujo másico dentro del volumen blanco (2).
