Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of petrochemical detection, more particularly to a portable oil tank liquid level automatic measuring instrument. BACKGROUND

[0002] The petrochemical industry is one of the pillar industries of the national economy, which not only provides a large amount of energy and chemical raw materials for the country, but also is an important force to promote industrialization and modernization. In the petrochemical industry, oil weight identification is an important means to ensure the quality and quantity of oil products. Through weight measurement, the mass of oil in the tank can be accurately determined to provide reliable data support for the trade, storage and use of petrochemical products. The oil tank liquid level is the main parameter of oil weight identification, and the measurement of this parameter needs to rely on accurate measuring equipment and tools.

[0003] There are two types of existing technologies for measuring the liquid level of an oil tank. One is manual measurement using a dipstick, and the other is non-contact automatic measurement using ultrasonic and radar technology. Non-contact automatic measurement devices are generally fixedly installed in the oil tank, which is inconvenient for calibration and maintenance. The measurement results often deviate from the actual liquid level, and are only used as reference data in the industry. The trade handover data industry still uses the manual measurement method which requires high accuracy. When measuring, the operator carefully lowers the dipstick and the dipstick tape along the special measurement port opened at the top of the oil tank. When the dipstick touches the tank bottom, the dipstick tape is recovered, and then the oil level is obtained by reading the oil mark formed on the dipstick tape. In order to ensure the accuracy of the measurement, multiple measurements are usually required. The manual method for measuring the liquid level of the oil tank has the following problems: complex operation: the operation process of using the dipstick for liquid level measurement is complicated and time-consuming. Moreover, the dipstick measurement is a contact measurement method, and the dipstick tape will be contaminated with oil, making it difficult to clean. Human factors have a great influence: the measurement results of the dipstick depend largely on the skills and experience of the operator. The measurement results of different operators may differ greatly. Reading error: the reading of the dipstick needs to be done manually, and the oil mark on the dipstick tape of some light oil is not clear enough, which may cause reading error. Therefore, there is a need to provide a portable oil tank liquid level automatic measuring instrument which is convenient to use, non-contact and high in precision. SUMMARY
