Abstract

Perfeccionamientos en aparatos integradores continuos para medir el volumen de flujo de fluido a través de un fluidimetro en una tubería, caracterizados porque se dota a cada aparato de un primer elemento de transmisión montado para girar alrededor de su eje, un segundo elemento de transmisión montado para girar alrededor de su eje, siendo uno de los elementos una rueda que tiene indentaciones formadas sobre su periferia, siendo el otro un elemento de radio de transmisión variable que tiene una superficie de transmisión de un material que presenta una baja deformación por compresión y una gran resistencia a la abrasión; un tercer elemento de transmisión montado para girar alrededor de su eje.
