Abstract

EL MEDIDOR COMPRENDE DOS TUBOS CON FORMA DE U (1,2) DISPUESTOS UNO AL LADO DEL OTRO ACOPLADOS RIGIDAMENTE Y TENIENDO SUS EXTREMOS INSERTADOS EN EL INTERIOR DE UN SOPORTE (3). LOS TUBOS (1,2) ESTAN ADAPATADOS PARA DIRIGIR EL FLUIDO EN CONTRACORRIENTE Y SE SUMINISTRAN CON UN ELECTROIMAN (4) ADAPTADO PARA PRODUCIR LA OSCILACION DE LOS TUBOS (1,2) ALREDEDOR DE UN EJE (A-A) QUE PASA A TRAVES DE LAS PARTES INSERTADAS DENTRO DEL SOPORTE (3), Y CON AL MENOS DOS BOBINAS (5,6), CADA UNA MIRANDO A UN IMAN PERMANENTE (7,8) PARA GENERAR UNA SEÑAL PROPORCIONAL AL ANGULO DE INCLINACION DE LA PARTE DE LOS TUBOS PEQUEÑOS (1,2) QUE SE OPONE AL SOPORTE (3) PARA PERMITIR ASI LA MEDIDA CONTINUADA DE LAS DIFERENCIAS DE CANTIDAD DE FLUJO DE MASA ENTRE DOS SECCIONES DEL TUBO.
