TECHNICAL FIELD
[0001] The present application relates to the technical field of horizontal storage tank metering, and in particular to a test device and method for simulating a cheating scenario of horizontal storage tank metering. BACKGROUND
[0002] Horizontal storage tanks are widely used for storing liquid petrochemical products, and are also used in the transportation and metering processes, mainly including horizontal buried tanks in gas stations, horizontal ground tanks in production enterprises, railway tank cars, and automobile tank trucks. In order to effectively control the process or carry out trade settlement, the liquid in the horizontal storage tank must be accurately metered. In actual application, the horizontal storage tank can be used as a container and as a measuring instrument (at this time, a liquid level meter and related instruments are usually provided) to realize liquid quantity metering. As a measuring instrument, the horizontal storage tank needs to be calibrated first. This process is called metering calibration. The metering calibration is generally carried out in accordance with the metering verification regulations such as JJG 266 “Horizontal Metal Tank Capacity”, JJG 140 “Railway Tank Car Volume”, and JJG 133 “Automobile Tank Car Capacity”. However, in recent years, cheating behaviors in horizontal storage tank metering have occurred frequently, which seriously interferes with the development of metering trade and metering calibration.
