Description
technical field [0001] The invention belongs to the technical field of automatic metering of crude oil storage tanks, and in particular relates to an automatic metering device and method for a crude oil storage tank elevator. Background technique [0002] At present, the detection of liquid level, interface level, layered water content and accurate measurement of oil volume in oilfield crude oil storage tanks are a major problem that plagues production, measurement, and management personnel, especially when there is an oil-water transition zone in the tank. It is difficult to detect and determine the position of the oil-water interface. The monitoring and measurement of crude oil storage tanks mainly rely on manual measuring scales, single-function floating body level gauges, servo level gauges, magnetostrictive level gauges, differential pressure level gauges, ultrasonic level gauges, radar level gauges, Laser liquid level gauge, optical fiber liquid level gauge, nuclear r...
