The invention relates to a vertical spiral wing type water metering device, which comprises a shell, a water inflow channel and a water outlet channel, wherein the water inflow channel and the water outlet channel are respectively horizontally arranged on two sides of the shell, a cavity is arranged between the water inflow channel and the water outlet channel, a metering component is vertically arranged in the cavity, the middle of the metering component is connected to an inside wall of the cavity in a sealing manner, the water inflow channel is communicated to the lower part of the metering component, the water outlet channel is communicated to the upper part of the metering component, the metering component comprises a filter water mesh, a lower fluid director, wing wheels and an upper fluid director, wherein the filter water mesh, the lower fluid director, the wing wheels and the upper fluid director are arranged successively back and forth from bottom to top; the metering component also comprises an edge side pressure reduction channel close to the inside wall of the cavity and an adjuster, size of the edge side pressure reduction channel can be adjusted by the adjuster, and volume of the water flow practically measured by the metering component can be further adjusted. In the vertical spiral wing type water metering device, practical volume measured by the water metering device can be adjusted through the edge side pressure reduction channel and the adjuster, therefore, measurement accuracy can be improved, moreover, installation and maintenance are very convenient.
