ABSTRACT:
A liquid separator allows a mixture of oil and water to separate, then discharges the two fractions. A separating tank is automatically filled when a float indicates a low level. A second float is close to the bottom of the tank and has a density such that the float will just float in water. The presence of oil causes the second float to sink; and, a switch connected to the float operates either a water valve when the float rises, or an oil pump when the density is low. Lowering of the level by discharging fractions causes the first float to indicate a low level to fill the tank again.
