Patent ID: 7159851

Claim:
An apparatus, comprising: a bi-directional DC motor; a gear reducer connected to the DC motor; a pulley mounted on an output of the gear reducer; an anti-back drive brake mounted on the output of the gear reducer; a reel wound with cable; a second pulley attached to the reel wound with cable; a belt for connecting the pulley and the second pulley; a water measuring device attached to an end of the cable wound on the reel; at least one shaft encoder attached to the motor for measuring the speed and direction of the motor; a DC power source connected to the DC motor; a microprocessor control electronics module connected to the at least one shaft encoder and the DC motor; and a remote control in communication with the microprocessor control electronics module, the remote control including a motor speed selector, the microprocessor control electronics module controlling a speed of the DC motor in either direction based on a setting of the motor speed selector and feedback from the at least one shaft encoder, the microprocessor control electronics module calculating speed corrections and an amount of the cable unwound or retrieved from the reel.
