Abstract

A tank battery metering management system is characterized in that the system comprises a magnetostrictive liquid level gauge with average temperature, an average thermometer, a modular converter unit, a communication cable, an epigyny supervisor, a printer, an UPS power supply and an oil tank measuring system software; the working method comprises (1) liquid level measurement; (2) volume calculation; (3) temperature measurement; and (4) volume correction; the system has the advantages that various physical parameters of oils in an oil tank can be automatically obtained from a computer; the whole precision of the system can reach 0.08 %; remote monitoring can be realized by networks such as an ADSL, dialing and the like; the system is the digital product, bus type wiring, and has strong network extended capability; the communication interface of the software is transparent and can be connected with other systems and software; the precision of the liquid level and the water level of the oils measured by a liquid level method is high, thus, the measured volume precision and the measured quality precision are high.

Description

(1) Technical field: [0001] The invention belongs to a measurement management system, in particular to a tank group measurement management system. (2) Technical background: [0002] For a long time, the petroleum industry has always adopted the measurement methods of manual measurement, manual sampling, and manual calculation for various oil products stored in oil tanks. Using manual methods, the workload is large, the work efficiency is low, and errors are prone to occur. With the rapid development of computer technology and the wide application of 3C technology, automatic metering gradually replaced manual metering, gradually forming a tank metering system in today's sense. (3) Content of the invention: [0003] The purpose of the present invention is to design a tank group measurement management system, which adopts a field bus type fully digital system, and can automatically obtain various physical parameters of the oil products stored in the oil storage tank from the comput...
