Description
技术领域 technical field
本实用新型涉及一种油水液面的新型测量装置，属于测量工具领域。 The utility model relates to a novel measuring device for the oil-water level, which belongs to the field of measuring tools.
背景技术 Background technique
近些年，随着科技水平的日新月异，石油工业的飞速发展，油水界面检测领域又引进了许多高新技术，比如超声波、雷达、光纤、计算机、微电子、传感器等。国内外学者也纷纷研究出基于不同原理的油水界面检测装置，使油罐液位测量已经进入了智能化、多功能、高精度的新阶段。当前，根据测量方法的不同，国内外油罐液位测量仪表可分为接触式和非接触式两种类型。 In recent years, with the rapid development of the technological level and the rapid development of the petroleum industry, many high-tech technologies have been introduced in the field of oil-water interface detection, such as ultrasonic, radar, optical fiber, computer, microelectronics, sensors, etc. Scholars at home and abroad have also developed oil-water interface detection devices based on different principles, making the liquid level measurement of oil tanks into a new stage of intelligence, multi-function and high precision. At present, according to different measurement methods, domestic and foreign oil tank liquid level measuring instruments can be divided into two types: contact type and non-contact type.
然而，非接触性测量方法较为复杂，成本高，受外界影响较大。接触性测量方法中，目前我国的原油储罐大都还在使用人工检尺进行测量，但其误差大，效率及安全系数低。其他测试方式也存在一些缺陷，比如电容液位仪测量方式，容器内工作湿度、温度、压力、电极腐蚀等因素都会影响测量的精度，且成本较高，工作寿命不是很长。磁致伸缩式界面检测方式采用接触式测量，要在原油罐内部安装电极，若电极损坏，不易更换。且检测装置中的浮子容易与原油沾结在一起，影响其磁性。浮子式界面测量方式只能测量原油界面的液位，很难测量油水界面位置。 However, the non-contact measurement method is more complicated, the cost is high, and it is greatly affected by the outside world. Among the contact measurement methods, most of the crude oil storage tanks in my country are still measured by manual rulers, but the errors are large, and the efficiency and safety factor are low. There are also some defects in other test methods, such as the measurement method of the capacitance liquid level meter, the working humidity, temperature, pressure, electrode corrosion and other factors in the container will affect the accuracy of the measurement, and the cost is high, and the working life is not very long. The magnetostrictive interface detection method adopts contact measurement, and electrodes must be installed inside the crude oil tank. If the electrodes are damaged, they are not easy to replace. And the float in the detection device is easy to stick together with crude oil, which affects its magnetic properties. The float interface measurement method can only measure the liquid level of the crude oil interface, and it is difficult to measure the position of the oil-water interface.
