Resumen (es)
En este artículo se realiza una revisión de los principios de medición de nivel de líquidos y sólidos que pueden llegarse a encontrar en el ámbito industrial. En primer lugar, se realiza una clasificación de las fuentes consultadas, dando a conocer el área de investigación a la que pertenece cada una. Seguidamente se muestran las definiciones clave en la instrumentación de nivel: sistema de medición, instrumento indicador, sensor y transmisor inteligente. Luego se da a conocer en qué consiste la medición de nivel de punto y la medición de nivel continua dos formas de medición de niveles bien diferenciadas, las cuales rigen el funcionamiento de un medidor. Posteriormente se describe el principio de medición de cada uno de los medidores de nivel, dando a conocer: partes básicas, el principio de funcionamiento, y en algunos casos el modelo físico-matemático que representa el comportamiento del medidor. Finalmente, se muestran las conclusiones del trabajo, exponiendo críticamente la revisión obtenida de modo que sirva como método orientador para ampliar la investigación realizada a medida que aparezcan nuevos desarrollos o innovaciones en la materia
Resumen (en)
This article presents a review of the principles of level measurements in liquids and solids that can be found in the industrial scope. First, one has to realize a classification of consulted sources, presenting the area of research to which each one belongs to. Later the key definitions are shown in level instrumentation measurement systems, indicating instrument, intelligent sensor and transmitter: Then it is shown what the measurement point level and continuous level measurements are, there are two ways of measuring, well differentiated levels, which govern the operation of a meter. Subsequently, the measuring principle of each meter levels are shown as: basic parts, the operating principle, and in some cases the physical-mathematical model representing the behavior of the meter. Finally, the conclusions of the work are critically exposing the obtained reviews so that it serves as a guiding method for expanding research as new developments or innovations appear in the matter.
