Abstract
A hog feeder having dry feed fed by gravity to a trough includes a supply of water thereto. A liquid sensor, relay and solenoid valve are used to maintain the water in the trough at a predetermined level. The liquid sensor used to maintain the liquid level at a predetermined level includes an electrically operated sensor that does not malfunction due to abuse by hogs or due to becoming caked with dirt or feed.
