液面是石油和化学工业生产过程中的重要参数之一,特別是在石油工业中,液面的測量和控制更有其头等的重要意义。在石油炼油厂中油罐这种設备为数是很多的,原油从罐中不断地送入加工車間,加工出的成品油又源源不断地送入罐中儲存;另外,成品油还要运往全国各地,因此,罐中的油量总是在变化的。通过对罐中油位的測量,可計算出罐中油的变化量以及罐中存有的油量。罐中油位測量要求迅速准确,它关系到生产班組,工段以及車間的定額完成情况,同时也关系到国家計划的完成情况和經济核算等問題。
Liquid level is one of the most important parameters in the production process of petroleum and chemical industry. Especially in the oil industry, the measurement and control of liquid level have more important significance. In the oil refineries in the oil tank this equipment is a lot, the crude oil from the tank continuously sent to the processing plant, processing of refined oil and a steady stream of tank storage; In addition, refined oil also shipped to the country Therefore, the amount of oil in the tank is always changing. By measuring the oil level in the tank, the amount of oil change in the tank and the amount of oil stored in the tank can be calculated. The oil level measurement requirements in the tank are prompt and accurate. It is related to the quota completion of the production team, the work section and the workshop, as well as the completion of the state plan and economic accounting.
