Abstract

The present invention relates to a device for measuring only pure oil from which air is completely separated by a positive displacement (PD) meter (h), wherein the air is discharged from the oil flowing along an arrow of a drawing 1 through a motor valve (b) opened and closed according to the operation of a level sensor and an air discharging pipe (i), but the device closes the motor valve (b) and opens an electronic butterfly valve (f) when the level sensor (d) sends the signal meaning that a vortex-type air separating tank (C) is filled with the oil to an electronic counter (g). Even while the operation mentioned above is performed, bubbles generated by cavitation in a pump for a supply side are always discharged by an air eliminator (a). The flow rate discharged from the PD meter (h) is displayed on a screen of the electronic counter (g) after the signal receiving from an encoder of the PD meter (h) is calculated by a formula programmed in the electronic counter (g). Temperature information receiving from a temperature sensor (e) is displayed on the screen as temperatures which are converted by a15 conversion formula programmed in the electronic counter (g). A program installed in the electronic counter (g) discharges air through the motor valve (b) and the air discharging pipe (i) when receiving the signal of the level sensor, and displays the discharge speed per minute of the PD meter (h) while performing the operation mentioned above.

Description

입고용 오일미터{Reception meter} Oil meter for wearing {Reception meter}

본 발명은 전자식오일미터 와 볼텍스타입 공기분리탱크, 온도센서, 레벨센서, Air Eliminator, 전동 버터플라이 밸브를 이용하여 완전하게 공기가 분리되고 실제 온도와 상관없이 15℃로 환산된 유류의 체적을 측정하는 방법에 관한 것이다. The present invention uses the electronic oil meter and vortex-type air separation tank, temperature sensor, level sensor, air eliminator, electric butterfly valve to completely separate the air and measure the volume of oil converted to 15 ° C regardless of the actual temperature. It is about how to.

일반적으로 유류저장소, 유류저장 바지, 주유소 등의 저장 탱크에 입고되는 유류 는 정유사에서는 15℃ 로 환산되어 출하되지만 유통과정에서 운송용 탱크로리, 유조선 등은 순수한 계량척에 의존하여 입고를 하므로 온도 1℃에 약 0.09%의 체적의 변화가 생기고 또한 출고하는 차량 및 유조선에 출고용 계량기가 설치되 어 있어도 자동 온도 변환장치가 없으며 적재해온 유류의 마지막 잔량을 배출시 키기 위해서 엔진을 급가속 (일명 후까시)시켜서 유류와 공기가 섞여 계측이 되므로 이것을 방지하고 정확한 유량을 계측하기 위한 기술이다. Generally, oils that are put into storage tanks such as oil depots, oil storage pants, gas stations, etc. are converted to 15 ° C at refineries, but tank lorry and tankers for transportation depend on pure weighing scales. Even if the volume change of about 0.09% occurs, and the shipping meter is installed in the vehicle and the oil tanker, there is no automatic temperature converter, and the engine is rapidly accelerated (aka back) to discharge the last remaining amount of oil loaded. Since oil and air are mixed and measured, it is a technology to prevent this and to measure accurate flow rate.

본 발명은 Positive Displacement Meter 와 Electronic Counter 의 결합으로 The present invention is a combination of Positive Displacement Meter and Electronic Counter

이루어진 전자식 오일미터에 15℃ 온도 환산식을 프로그램하여 자동으로 환산된 유량을 측정하고, Vortex 방식의 공기분리탱크와 Air Eliminator,를 결합하여15 ℃ temperature conversion formula is programmed in the electronic oil meter, and the flow rate is automatically converted.Vortex type air separation tank and air eliminator are combined.

Cavitation 으로 발생하는 기포 및 기타 흡입되는 공기를 Air Eliminator 를 통하여 By-pass 라인을 통하여 배출을 시키고 Vortex 방식의 공기분리탱크에 유류가 가득 채워지면 Air Eliminator 의 배출구는 막힘과 동시에 Level SensorAir bubbles and other inhaled air are discharged through the bypass line through the air eliminator. When the oil is filled in the vortex-type air separation tank, the outlet of the air eliminator is blocked and the level sensor

의 신호를 받은 Electric Butterfly valve 열리고 실시간으로 흐르는 유류의 온도를 감지한 온도 sensor의 신호를 받아서 자동환산된 순수한 유류만 공급되는 측정 방식이다. Electric Butterfly valve which receives the signal of the open and receives the signal of the temperature sensor which senses the temperature of the flowing oil in real time.

PD Meter 와 Electronic Counter에 온도센서를 사용하여 실시간으로 검출된 온도정보를 15℃ 환산수량으로 변환하도록 ,Electronic Counter 에 프로그램하여 공급되는 실량이 표시되며 레벨센서,전동 밸브 등으로 이루어진 System 을 이용하여 Vortex 방식의 공기분리탱크와 Air Eliminator 통하여 Cavitation 으로 발생하는 기포 및 기타 흡입되는 공기를 By-pass 라인을 통하여 배출을 시키고 , 공기 분리탱크 에 유류가 가득 채워져서 Level Sensor 가 작동을 시작하면 Air Eliminator 의 배출구는 막힘과 동시에 Level Sensor 의 신호를 받은 Electric Butterfly valve 열리고 실시간으로 흐르는 유류의 온도를 감지한 온도 sensor의 신호를 받아서 자동환산된 순수한 유류만 공급되는 측정 방식이다. The actual quantity supplied to the Electronic Counter is displayed to convert the temperature information detected in real time using the temperature sensor on the PD Meter and the Electronic Counter into 15 ℃ equivalent.The Vortex system is made up of a system consisting of a level sensor and an electric valve. Through the air separation tank and air eliminator, air bubbles and other inhaled air are discharged through the by-pass line.When the level sensor starts because the air separation tank is filled with oil, the outlet of the air eliminator Electric Butterfly valve which is blocked and at the same time open the Electric Butterfly valve and receives the signal of the temperature sensor which senses the temperature of the flowing oil in real time.

Positive Displacement Meter 와 Electronic Counter 로 결합된 전자식 오일미터에 15℃ 온도 환산된 프로그램과 Vortex 방식의 공기분리탱크와 Air Eliminator 를 결합하여 Cavitation으로 발생하는 기포 및 기타 흡입되는 공기를 Air Eliminator 를 통하여 By-pass 라인을 통하여 배출을 시키고 공기분리탱크에 유류가 가득 채워져서 Level Sensor 의 신호를 받음과 동시에 Air Eliminator의 배출구는 막히고 Electric Butterfly valve 는 열려서, 실시간으로 흐르는 유류의 온도를 감지한 온도 sensor의 신호를 받아By using the electronic displacement meter combined with the Positive Displacement Meter and the Electronic Counter, the program converted to 15 ℃ temperature, the Vortex type air separation tank, and the air eliminator are used to pass bubbles and other inhaled air generated by cavitation through the air eliminator. It discharges through the line, and the air separation tank is filled with oil to receive the signal from the level sensor. At the same time, the outlet of the air eliminator is blocked and the electric butterfly valve opens to receive the signal from the temperature sensor that senses the temperature of the oil flowing in real time.

*,유류의 공급자인 정유사에서는 온도환산 방식으로 소비자에게 출하를 한다.*, Oil refinery, the supplier of oil, is shipped to consumers in a temperature conversion method.

(예 : 정유사 출하시 온도 15℃ 에서 20,000리터를 적재해서 뜨거운 햇볕 을 (E.g., 20,000 liters of oil at the factory's temperature of 15 ℃

받으며 몇 시간 달려서 수급자에게 도착 했을때 실 온도가 25℃ 면 체적이 불어나서 20,180리터 되어야하지만 수급자들이 확인 할수있는 것은 탱크로리에 부착된 When you arrive at the recipient after a few hours of running, the actual temperature should increase to 20,180 liters when the temperature rises to 25 ℃, but the recipients can confirm that they are attached to the tank lorry.

20,000가 표시된 계량척 밖에 획인 할수있는 방법 외에는 없다) 이와같이There is no other way than to capture 20,000 marked scales)

소비자들만 일방적으로 불리하게 되어 있는 유통구조의 문제점을 해결하기 위해서는 정유사에서 소비자 (급유소, 공기업, 사기업)에게 입고 시 유량을 정확하게 측정 할수 있는 본 기술을 이용하면 문제해결이 가능하다. In order to solve the problem of the distribution structure that only the consumers are disadvantaged unilaterally, it is possible to solve the problem by using this technology that can accurately measure the flow rate at the refinery to the consumers (gas stations, public enterprises, private companies).

*,관공서, 공기업 및 군부대의 경우 유류를 입고할 때 입고되는 유류량이 정확한지 확인 할 수 있는 계량기가 없음과 관리자의 잦은 부서이동 인해 관리자가 유류 입고 방법을 잘 모르는 경우가 있을 수 있다. 또한 일반 주유소에서도 동일하다* In the case of public offices, public enterprises and military units, there may be cases where there is no meter to check whether the amount of oil received is correct when wearing the oil, and the manager may not know how to receive the oil due to frequent movement of the department. The same is also true for gas stations.

따라서 다음과 같은 문제점이 발생될 수 있으며 이를 방지하기 위한 기술이다.Therefore, the following problems may occur and it is a technique for preventing this.

* 유류 입출고시 불투명한 거래 * Opaque transaction at the time of oil import and export

* 정량의 유류가 입고되지 않음으로 인한 예산 낭비 * Waste of budget due to not receiving quantity of oil

* 재고관리의 불확실성 * Uncertainty in inventory management

* 정유사에서 급유소에 오는 유통과정에서 문제가 발생 할 수 있음* Problems may arise in the distribution process from oil refineries to gas stations

* 유조선 & 탱크로리 운전기사가 유량을 조절 * Oil tanker & tank lorry driver regulate the flow

* 급유소 측의 관리자가 유량을 조절
* The manager of the gas station adjusts the flow rate
