ABSTRACT:
Apparatus is provided for preventing reaction forces on a flow control valve from affecting measurements of particulate feed rate, where such measurements are made using weighing devices to determine the amount of particulates in a supply container as a function of time. The apparatus includes means for applying sufficient compressive prestress to spacer bars for absorbing reaction forces on the valve so that extension of the staybars is prevented during particulate feeding. Movement of the container due to reaction forces on the valve is prevented and particulate feed rate errors are substantially eliminated.
