ABSTRACT:
A method and apparatus for regulating electrolyte solution level in a liquid rheostat. The liquid rheostat is used to control the motor speed of a primary pump which is operable for pumping liquid from a well. The liquid rheostat includes an electrode compartment mounted above an electrolyte solution reservoir and solution from the compartment may drain into the reservoir. A conduit interconnects the reservoir with the compartment and a circulating pump, driven by a variable speed electric motor, is operable for delivering solution from the reservoir to the compartment. A sensor is immersed in the well and develops a signal proportional to the amount of liquid in the well. The signal is received by a motor control which operates to vary the speed of the circulating pump motor, and thus the solution level in the compartment, reflective of liquid level in the well.
