Abstract

INSTALACION PARA LA MEDICION DE LA CIRCULACION DE FLUIDOS BIDIRECCIONAL. CONSTA DE UNA CAJA (12) HECHA DE UN MATERIAL NO MAGNETICO QUE RODEA A UN CANAL DE CIRCULACION; DE UN PRIMER CUERPO DE ESTRANGULACION (32) DISPUESTO EN EL CANAL DE CIRCULACION, QUE FORMA UN ESTRECHAMIENTO VARIABLE CON UN SEGUNDO CUERPO DE ESTRANGULACION (66) DISPUESTO A CIERTA DISTANCIA DEL PRIMERO, SIENDO DESPLAZABLES UNO DE LOS CUERPOS DE ESTRANGULACION CON RESPECTO AL OTRO; Y DE UNA DISPOSICION ELASTICA DE MUELLES (88, 90) QUE OPRIME AL CUERPO DE ESTRANGULACION DESPLAZABLE (66) HACIA SU POSICION NEUTRA. DICHO CUERPO DE ESTRANGULACION DESPLAZABLE (66) TIENE LA FORMA DE UN MANGUITO O CASQUILLO Y RODEA AL PRIMER CUERPO DE ESTRANGULACION (32).
