Abstract

El presente invento tiene por objeto un medidor de gas que comprende un conducto de medicion ultrasonoro de eje longitudinal que posee una parte internadentro de la cual fluye el flujo de gas, por lo menos dos transductores ultrasonoros espaciados alo largo del eje longitudinal, caracterizado porque dichomedidor comprende entre cada transductor y dicha parte interna del conducto de medicion de una porcion ensanchada con respecto a las dimensiones de lasuperficie activa de dicho transductor, comprendiendo dicho medidor además por lo menos un elemento dispuesto en por lo menos una de dichas porcionesensanchadas que se extiende por toda la dimension interna de manera de formar una pantalla filtrante enfrentada a los polvos transportados por el gas, siendodicho elemento atravesado por las ondas ultrasonoras emitidas por los transductores sobre por lo menos una parte de su ancho, el cual es superior a lasdimensiones de la superficie activa de dicho transductor.A subject of the present invention is a gas meter comprising a longitudinal axis ultrasonic measuring conduit having an internal part within which the gas flow flows, at least two ultrasonic transducers spaced along the longitudinal axis, characterized in that dichomeditor it comprises between each transducer and said internal part of the measuring duct of a widened portion with respect to the dimensions of the active surface of said transducer, said meter further comprising at least one element disposed in at least one of said widened portions which extends by the entire internal dimension so as to form a filter screen facing the powders transported by the gas, said element being traversed by the ultrasonic waves emitted by the transducers over at least a part of its width, which is greater than the surface dimensions active of said transducer.
