Problems solved by technology

The problems with this standard method are: 1. It takes about 2 hours to make a sample, and real-time online measurement cannot be done; 2. Since all the steps of the above-mentioned distillation method for determining moisture content are manual operations, it is difficult to design an online method based on this method. Automatic Measuring Device or System
[0005] The lack of real-time monitoring means for the moisture content of refined oil in the refined oil depot (tank) and the rapid determination method and device for the moisture content of the oil sold by the refined oil vending machine are two major technical problems that plague the effective supervision and timely law enforcement of the refined oil market

Embodiment Construction

[0015] The measurement method is as follows: first, the ultrasonic non-contact distance measurement principle is used to measure the liquid level of the refined oil in the container, then the pressure of the refined oil in the container is measured according to the signal of the differential pressure sensor, and finally the water content of the refined oil is comprehensively calculated by an embedded computing device.

[0016] The measuring device as figure 1 As shown, it is mainly composed of an embedded computing device 1, a differential pressure measuring device 2, an ultrasonic liquid level measuring device 3, an ultrasonic probe 4, and a differential pressure sensor 5. The ultrasonic probe 4 is installed near the center of the top of the refined oil depot 10, and the ultrasonic probe 4. Connect the ultrasonic liquid level measuring device 3; install the liquid pressure introduction pipe 8 near the central position near the bottom of the finished oil depot 10 or the finishe...

Said measurement equipment includes the following several portions: tank dome, ultrasonic probe, ultrasonic level measuring device, liquid pressure intensity pressure-guiding pipe, air pressure intensity pressure-guiding pipe, pressure difference sensor, differential pressure measuring device and computer. Said invention also provides its working principle and its operation method and steps.

Description

Technical field [0001] The invention relates to a measuring method and device, in particular to an online real-time measuring method and device for the water content of refined oil. Background technique [0002] In the era of planned economy and the early stage of reform and opening up, relevant government departments were responsible for oil exploration, collection, refining, and storage, transportation, and sales of refined oil. Detection control. The proportion of private enterprises and private vehicles is very small, and the national gas stations are all state-owned enterprises of the same system. No cash is accepted for refueling vehicles, only fuel tickets are accepted. The quality of refined oil, especially the water content, is basically above the qualified standard. , people feel that there is no need to monitor the quality and actual water content of refined oil products in the storage, transportation and sales of refined oil products. [0003] In the past ten y...
