ABSTRACT:
An apparatus and method for detecting and handling liquid separation in a liquid emulsion disposed in a tank 1 by preventing separated liquid from entering a withdrawal conduit 3 disposed in the lower portion of the tank 1 by a apparatus comprising a pump 9 driven by an electric motor 15 and taking its suction form the lower portion of the tank 1 and discharging adjacent the central portion of the tank 1, a float 5, which sinks in the emulsion and floats on the high density liquid is cooperatively associated with a relay 17 to start the pump motor 15 when accumulated high density liquid raises the float 5 a predetermined amount, a time delay 21 runs the pump 9 a predetermined length of time sufficient to reemulsify the accumulated high density and preventing it from entering the withdrawal conduit 3.
