Abstract
An agent distribution system includes a water tank, a flush line, a flush valve, an agent storage tank, an agent line, an agent valve, a first flow meter, and a second flow meter. The flush line receives water from the water tank. The flush valve is configured to selectively prevent water from flowing along the flush line downstream of the flush valve. The agent line receives agent from the agent tank. The agent valve is configured to selectively prevent agent from flowing along the agent line downstream of the agent valve. The flush line extends into the agent line at a junction. The junction is disposed downstream of the agent valve. The first flow meter is positioned along the agent line downstream of the junction. The second flow meter is positioned downstream of the first flow meter and upstream of a discharge system.
