Abstract

Aparato para la medición del caudal de fluido en un conducto, particularmente apto para la medición del caudal del aceite de alimentación de un cable eléctrico con aceite fluido, constituido por un cuerpo con cavidad pasante y que comprende una primera y una segunda cámaras inter comunicantes a través de una lumbrera oportuna y un medio apto para detectar diferencias de presiones existentes entre estas dos cámaras, caracterizado por el hecho de comprender medios movibles al menos transversalmente a la dirección del flujo aptos para separar la primera de la segunda cámaras y para variar la lumbrera, y medios para actuar sobre estos medios movibles en manera de mantener entre dichas cámaras una diferencia de presión prefijada y constante para cualquier valor y sentido del flujo.
