The utility model provides a spiral wing type water meter, belonging to the measuring technical field. The utility model solves the problem of low assembly efficiency of the existing screw wing type water meters. The spiral wing type water meter, and comprises a core component case, core assembly comprises a bracket with circular pipe, the case with the installing cavity; pipe outer mask along the circular tube portion extends circumferentially between the spoiler, spoiler and side movement left side mounting cavity flow space. The resistance to flow with plugging flow space of the fixing plate of the spoiler bars. The spiral vane type water meter can not only ensure the low flow performance of the measurement flow, but also ensure the measurement to be lowered; and when the water meter is suitable for large flow, the impact of the overload current on the mechanism is ensured. The spiral vane water meter also has the advantages of convenient assembly.
