Problems solved by technology

[0003] However, in the existing detection device for fuel dispensers, some residual fuel will stick to the inner wall of the device, which will affect the next detection result. The calculated value is relatively simple, and there is no comparison, which will cause errors. At that time, there was no equipment for testing the level, and only the oil temperature at the oil outlet of the oil gun could be detected, which was far from meeting people's current requirements for the product. Therefore, how to design a fuel oil detection device based on temperature control has become The problem we are currently trying to solve

Embodiment Construction

[0024] The present invention will be further described below in conjunction with specific embodiments, wherein, the accompanying drawings are only for illustrative purposes, please refer to Figure 1-Figure 4 , the present invention provides a technical solution: a fuel oil detection device based on temperature control, including a standard metal gauge 1, the surface of the inner cavity of the standard metal gauge 1 is provided with a non-stick coating 2, which can prevent the fuel from sticking The inner wall of the standard metal gauge 1 will not affect the detection result due to the combination of the oil sticky on the inner wall and the oil added again, which improves the accuracy of the data. The top of the standard metal gauge 1 is fixedly connected with a metering neck 3, The top of the metering neck 3 is sleeved with a liquid flow meter 4, which can measure the amount of fuel flowing through the metering neck, and calculate the volume through the flow rate, which can b...

Abstract

The invention discloses a fuel oil detection device based on temperature control, which comprises a standard metal gauge, the surface of the inner cavity of the standard metal gauge is provided with an oil-free coating, and the top of the standard metal gauge is fixedly connected with a metering neck. A liquid flowmeter is sleeved on the top of the metering neck, a first temperature sensor is installed through the front surface of the overflow cover, an oil gun fixing frame is provided on one side of the overflow cover, a liquid level sensor is provided on the top of the sensor placement tube, and the sensor is placed There is a second temperature sensor on one side of the tube. This device uses the internal amplifier A as a comparator through a high-precision temperature control circuit. It only needs to ensure that the current limiting resistor is relatively large, and its temperature control circuit has lower requirements, and can measure the standard The temperature of the fuel oil in the metal gauge can be compared with the temperature data of the oil outlet from the nozzle of the fuel gun measured by the first temperature sensor, and then more accurate temperature data can be calculated, data errors can be reduced, and the accuracy of the device can be improved.

Description

technical field [0001] The invention relates to the technical field of fuel dispenser automatic detection, in particular to a fuel detection device based on temperature control. Background technique [0002] With the rapid development of highway traffic in our country, gas stations are spread all over the road, so the inspection of fuel dispensers has become a heavy task for the quality and technical supervision department. The verification agency will test it, and it will take about ten days for the gas station to perform self-calibration for each fuel dispenser. The detection and self-calibration are both carried out by the comparison method of the standard measuring device, that is, the oil from the fueling gun is poured into the standard measuring device , by comparing the indicated value of the oil volume of the tanker with the indication of the liquid level of the standard gauge to check the exact condition of the tanker to determine whether the tanker is qualified or ...
