Abstract
A system for automated water drainage in a fuel system includes a fuel-water separator, a water sensor, first and second drain valves, a drain pressure sensor, and a control system, which is operably connected to the first and second drain valves, the water sensor, and the drain pressure sensor. The water sensor is disposed in the fuel-water separator for detecting the presence of water. The first drain valve is in fluid communication with the fuel-water separator, and the second drain valve is in fluid communication with the first drain valve; a fluid duct connects the first and second drain valves. The drain pressure sensor is positioned in the fluid duct, for detecting pressure levels in the fluid duct. The control system automatically operates the first and second drain valves, for removing purge liquid from the fuel-water separator, based on signal outputs of the water sensor and the drain pressure sensor.
