Abstract
A feeder containing animal feed uses feed removal equipment to remove feed at a known constant rate. This feed metering apparatus is used to indicate the amount of feed remaining in the feeder at any time. This apparatus is operated to move a pointer indicating feed quantity only when feed is actually being removed from the feeder. The movement of the pointer is adjusted to correspond to feeder rates for different feeder equipment either by adjusting the duty cycle of a motor driving the pointer to different percentages of the feeder equipment operating time, or by adjusting the motor rpm rate, either by using an adjustable frequency changer to drive an ac motor, or by changing the power from ac to dc and using dc to drive a speed adjustable dc motor.
