A method and apparatus are described for accurately measuring the weight of a moving stream of particulate material at different flow volumes. The apparatus includes a dynamic measurement device with a deflectable curved pan for measuring the amount of material flowing along a pathway; a supply source for discharging material along the pathway; and a gate valve having an inclined gate member with a leading edge controlling the volume of material discharged from the supply source, the valve reducing the height of discharge of the material above the dynamic measurement device proportional to the increase in the flow volume of material being discharged. A gate valve is also described that includes a gate member with a fully open position and a fully closed position, the valve aperture being open a width determined by the bridging characteristics of the particulate material being discharged when the gate member is in the fully closed position.
