Ultrasonic Flow Converters description

정밀 ToF(time-of-flight) 측정에 적합한 TDC(time-to-digital conversion) 기술을 기반으로 한 UFC 제품들은 트랜스듀서(transducer)를 구동하고 판독하기 위해 아날로그 프론트엔드를 동작하며, 수신 신호에서 제로 크로싱을 검출하여 시간 지연을 측정합니다. 전체 프론트엔드는 초저전력 동작에 적합하도록 최적화되었습니다. TDC-GP30은 유량을 계산할 수 있는 저전력 32비트 CPU를 통합했습니다. 통신을 위해GP30은 SIO, UART 또는 펄스 인터페이스를 제공합니다.
