ABSTRACT:
An apparatus for testing the functioning of a float-activated liquid level control device comprises a float for activating a liquid level control device, a float cage enclosing said float, an entry port accessible from outside a separating tank through which fluid may be input directly into the float cage enclosure, and a flange connection for mounting the test apparatus inside a fluid separation tank. The method comprises connecting a fluid source to the input port of the apparatus of the instant invention, injecting fluid directly into the float cage enclosure to activate the float of the instant invention, monitoring the liquid level control device to insure that it is functioning correctly and then withdrawing the input fluid to return the float to its normal operating position.
