Abstract

예컨대 수도관(10)용 유동탐지시스템은 유동탐지기 (11)와 이곳에서 나온 신호를 수령하는 제어회로(13)를 포함한다.
제어회로(13)는 일정기간동안 유속이 예정레벨 아래로 떨어진 경우 출력을 발생한다. 유속저하는 탐지기(11)의 수도관(10) 하류에 누수가 있음을 가리키는 것이며 제어밸브(15)는 제어회로(13)에 의한 출력발생시 폐쇄된다.

Description

유동탐지시스템
본 내용은 요부공개 건이므로 전문내용을 수록하지 않았음
제1도는 수도과 누수를 탐지하는 시스템의 다이어그램이다.

Claims (3)

  1. 유동탐지기(11)와 제어회로(13)를 포함하고 이 제어회로는 탐지유속에 따라 유동탐지기에서 나온 신호를 수령하여 이 유속이 사전결정 기간동안 역시 예정레벨보다 낮을때 출력을 발생하는 것을 특징으로 하는 유동탐지 시스템.
  2. 제1항에 있어서, 유동탐지기에 연결되고, 또한 탐지유속이 예정레벨보다 낮을 때를 기록하고 일정기간동안 이 경우가 기록되지 않았으면 출력을 발생하도록 프로그램된 프로세서가 제어회로(13)에 포함된 것을 특징으로 하는 유동탐지시스템.
  3. 유체공급관(10)속의 누수를 탐지하기 위해, a)관(10)을 통과하는 유속을 측정한 유동탐지기(11)와 또한 이 탐지기(11)로 부터 나온 신호를수령하는 제어회로(13)를 제공하고, b) 신호를저장하고, c) 일정시간후 그동안의 유동속도가 예정레벨보다 낮은 상태를 가리키는 신호가 발생되었는지 조사하고, d) 저장신호가 없을 경우
    누수를 알리는 출력신호를 발생하는 단계로 이루어진 누수탐지방법.
    ※ 참고사항 : 최초출원 내용에 의하여 공개하는 것임.
