Description
본 고안은 주유량 모니터링 장치에 관한 것으로서, 특히 운전자가 차량에 주유되는 연료의 실제 양을 모니터링할 수 있게 하는 주유량 모니터링 장치에 관한 것이다.The present invention relates to a fuel flow monitoring device, and more particularly to a fuel flow monitoring device that allows the driver to monitor the actual amount of fuel to be injected into the vehicle.
통상적으로, 차량의 연료탱크에 주입되는 연료량은 주유 머신의 미터기를 통해서만 확인이 가능하였다. 그에 따라, 비양심적인 업주나 종업원에 의해 미터기가 조작될 경우, 소비자들은 아무 대책없이 고스란히 손해를 볼 수 밖에 없었다.Typically, the amount of fuel injected into the fuel tank of the vehicle can only be confirmed by the meter of the fueling machine. As a result, when the meter was operated by an unscrupulous owner or employee, consumers were forced to lose money without any countermeasures.
한편, 대한민국 특허공개번호 제2002-0058785호 "주유량 확인장치"에는 "주유 머신의 주유건에 연결되는 연료호스의 외경에 장착 및 탈거되는 제1,2클램프; 상기 제1클램프에서 상기 연료호스를 경유하는 연료에 초음파를 발신하도록 상기 제1클램프에 내장되는 트랜스미터; 상기 트랜스미터에서 발신되어 연료 호스의 연료를 경유하면서 변화된 초음파를 수신하도록 상기 트랜스미터의 대향측 제2클램프에 내장되는 리시버; 상기 트랜스미터의 발신 신호와 리시버의 수신 신호를 가공, 제어 그리고 연산하도록 상기 트랜스미터와 상기 리시버에 전기적으로 연결되는 초음파 유량계 모니터를 포함하는 주유량 확인장치"가 개시된 바 있다.On the other hand, the Republic of Korea Patent Publication No. 2002-0058785 "Oil flow rate check device" includes "first and second clamps mounted and removed on the outer diameter of the fuel hose connected to the fuel gun of the fuel oil machine; and the fuel hose in the first clamp A transmitter embedded in the first clamp to transmit ultrasonic waves to the fuel passing through; a receiver embedded in the second clamp opposite the transmitter to receive the changed ultrasonic waves transmitted from the transmitter via fuel of the fuel hose; A gas flow rate identification device has been disclosed that includes an ultrasonic flowmeter monitor electrically coupled to the transmitter and the receiver to process, control and calculate the outgoing signal and the received signal of the receiver.
그러나, 상술한 바와 같은 종래의 주유량 확인장치는 실제 연료탱크에 주입되는 연료량이 아니라 주유 머신의 주유건을 통과하는 연료량을 감지하여 주유량을 확인하게 되므로, 주유원의 실수로 밖으로 새어 나간 연료량이나 주유 호스에 남아있는 연료량 등 실제 주유량과의 오차량은 감지할 수 없는 문제점이 있었다.However, the above-described conventional fuel flow rate checking device detects the fuel flow rate by detecting the fuel flow amount passing through the fuel injection gun of the fueling machine, not the amount of fuel injected into the actual fuel tank. There was a problem that the amount of error with the actual fuel amount, such as the amount of fuel remaining in the can not be detected.
상기와 같은 문제점을 해결하기 위하여 본 고안의 목적은 실제 연료통에 공급된 연료량을 정확히 판단할 수 있게 함으로써, 주유기의 미터기에 나타낸 주유량과 실제 주유량과의 차이를 명확히 하여 소비자의 피해를 미연에 방지하기 위한 주유량 모니터링 장치를 제공하는데 있다.In order to solve the above problems, an object of the present invention is to accurately determine the amount of fuel supplied to an actual fuel container, and to clarify the difference between the fuel amount indicated on the meter of the fuel tanker and the actual fuel amount to prevent consumer damage. To provide a fuel flow monitoring device for.
