Abstract

A radio controlled liquid monitor, capable of rotation about a vertical axis through an infinite arc is disclosed. A rotatable body is rotatably mounted onto a base element for rotation about a vertical axis, and a discharge elbow is rotatably mounted on the rotatable body for rotation about a horizontal axis. A horizontal drive unit and a vertical drive unit operate on gears on the rotatable body and the elbow, to enable the rotatable body to rotate about a vertical axis, and the discharge elbow to rotate about a horizontal axis. A control module is attached to the rotatable body which receives radio control commands from an operator via a portable transmitter apparatus or a fixed transmitter apparatus. The control module and drive unit receive electrical power and control signals through a rotating connector positioned within the base element and rotatable body so that the control module and drive units receive electrical power and control signals regardless of the rotational position of the rotatable body.
