- 레벨게이지 센서는 그 양단이 본체(110) 내에서 LNG의 하한 레벨(L1)과 상한(만충전) 레벨(L2)사이에 위치하도록 비스듬하게 설치하고,상기 상한 레벨은 상기 본체(110) 내의 상부쪽에 감량공간이 확보되는 위치에 설치하고, 상기 하한 레벨은 일정 연료가 잔류되는 위치에 설치하며, 상기 레벨게이지 센서의 내부에는 LNG 레벨에 따라 승하강하는 플로우트를 설치하고, 상기 레벨게이지 센서의 상단부에는 상기 플로우트가 접촉함에 따라 신호를 발생하는 단자를 설치하여, 상기 레벨게이지 센서 및 단자의 신호에 따라 솔레노이드 밸브를 온-오프하여 LNG 연료용기의 과충전을 방지하는 방법으로서,전원 및 회로 이상여부를 자가 진단하여 연료 충전을 시작할 것인지를 판단하는 제1단계(S1)와,일정시간동안 상기 레벨게이지 센서에 의해 감지되는 레벨변화의 유무에 따라 연료 충전을 계속할 것인지를 판단하는 제2단계(S2)와,상기 제2단계 후에 상기 레벨게이지 센서의 상한(만충전) 레벨 신호에 따라 충전을 계속할 것인지를 판단하여 연료의 과충전을 방지하는 제3단계(S3)와,상기 제3단계 후에 상기 플로우트가 상기 단자에 접촉함에 따라 솔레노이드 밸브를 닫아 연료충전을 중지하는 제4단계(S4)를 포함하는 것을 특징으로 하는 LNG 연료용기의 과충전방지방법.
- 청구항 1에 있어서,상기 레벨게이지 센서는 하한 레벨(L1)과 상한(만충전) 레벨(L2)이 각각 계기판(운전석의 계기판)에는 연료량 0%, 100%로 표시되게 하는 것을 특징으로 하는 LNG 연료용기의 과충전방지방법.
