A flow regulator and flow rate meter device for manifolds in heating systems; the device comprises a tubular casing (14) which can be screwed into the manifold body (10) in a position axially aligned to a branched duct (12); a plug (17) is movable with respect to a valve seat (18), and is screwably supported inside the tubular casing (14) between a forward closed position and backward open positions. A handgrip (25) of transparent plastic material, is operatively connected to the plug (17), while a flow rate indicator rod (26) is made visible and slides within the handgrip (25); the rod (26) penetrates into the branched duct (12) and is provided with a disk (27) subject to the entraining action of the flow. The plug (17) and the valve seat (18) are provided with opposite surfaces (17', 18') which extend axially into the branched duct (12), towards an annular shoulder (18") for diverting the flow against the disk (27) of the rod (26). |
