Abstract
An automatic digital backfat meter. An apparatus and method primarily for measuring the thickness of backfat in an animal which automatically adjusts sensitivity and notifies the user when a proper reading is obtained. The transducer (62) produces pulses which pass amplifier (64), threshold detector (68), and are counted in counter (74). If two counts are received, indicator (76) is activated. If two counts are not received, the cycle is repeated and the amplifier (64) has its gain increased by sensitivity control (66) in a stepwise increment until indicator light (76) is activated. Time delay (78) prevents the first echo from being counted at counter (74).
