Abstract

Se proporciona un flujometro (310) que considera el efecto de Coriolis, con sensibilidad aumentada, que tiene uno o más impulsos (D) que hacen oscilar un tubo de flujo (130) o tubos, (130, 130'), a frecuencias predeterminadas, por lo que producen nodos (N) que incluyen nodos activos (AN) y/o nodos estáticos (SN) en puntos a lo largo de los tubos de flujo (130, 130'). La cesibilidad aumentada del presente flujometro (310) se proporciona por censores (S) que se localiza de manera controlable en proximidad cercana a los nodos estáticos (SN) y/o nodos activos (AN). En una primera modalidad, los tubos de flujo (130, 130') se hacen oscilar de una manera que generen un nodo (AN) activo unico, con censores (S) colocados en proximidad cercana, y en lados opuestos de, el nodo activo (AN). En una segunda modalidad, los tubos de flujo (130, 130'), se hacen oscilar de una manera que generan nodos activos multiples (AN) en los que los sensores (S) se localizan en lados opuestos de cada nodo activo (AN), o en tubos de flujo opuestos(130, 130'), en el que un sensor (S) está por encima de un nodo activo (AN) sobre una pata y el segundo sensor (S) está por debajo del nodo activo (AN) en el extremo opuesto. En otra modalidad, los censores (S) se colocan en proximidad cercana con los nodos estáticos (SN) además de las posiciones de sensor (S) para nodos activos (AN) como se indica previamente. En todas las modalidades, los censores (S) se colocan de manera controlable proximos a los activos (AN) y/o a lo nodos estáticos (SN) de manera que maximiza la relacion de señal a ruido generada por los circuitos electronicos del sensor.
