The utility model provides a water gaging V -notch weir device with adjustable, relates to the water conservancy and irritates row irrigation canals and ditches accuse water yield water facilities field. With water retaining board and the flat capable closed assembly of water gaging V -notch weir in a frame, is rising or is choking water when being unfavorable for accurate measurements of weir when the channel water level, can lifting capacity mill weir height, made the sluice flow the free flow that can remain the ideal throughout and measured the state, create can be accurate measurement conditions. When water retaining board promoted at the water gaging weir plate, can stop the channel rivers must just can flow past through the weir measurement. Traditional drawback of V -notch weir volume water facilities has been overcome to adjustable weir, has changed the applied defect of traditional weir in the metering method, and perfect irrigated area channel water resource metering facility deepens reforms for ch
