Metering and release trailer (left) has four pipes (0.5-in., 2-in., 4-in., and 8-in.), each leading to a distinct metering location allowing a different dynamic range of release volumes. The three larger pipes used a QuadraTherm 640i insertion meter (right), with upstream 8.5 m straight run of pipe to ensure sufficient flow stabilization for all pipes. The 0.5-in. pipe was not used in this study.
