Embodiment Construction
[0068] The present invention will be described in detail below in conjunction with specific implementation and accompanying drawings. The normal pressure vertical cylindrical vaulted tank used in the implementation of this example, stored in the tank is environmental protection aromatics oil VIVA. According to the liquid level quality measurement method, the implementation of this example requires a liquid level sensor and a temperature sensor. The liquid level sensor is installed on the top of the tank with a radar level gauge, and the temperature sensor is installed in the middle of the inner wall of the tank.
[0069] Such as Figure 1-4 As shown, the online calculation device for calculating the quality of oil and gas liquid chemicals in storage tanks by liquid level method is characterized in that it includes ARM microprocessor, power supply / reset circuit, UI circuit, SDRAM, NORFLASH, RJ45 network port, HDMI interface and two One RS485 interface. The signal output end o...

An on-line computation device utilizing a liquid level method for computing storage tank oil gas liquid chemical weight is a weight on-line automatic metering device and characterized by comprising an advanced reduced instruction-set computer (RISC) machine (ARM) microprocessor, a power source / reset circuit, a user interface (UI) circuit, a synchronous dynamic random access memory (SDRAM), a NOR Flash, an RJ 45 internet access, a high-definition multimedia interface (HDMI) interface and an RS 485 interface. According to combination of software and hardware, weight on-line computation of storage tank liquid is achieved and instantaneity and truth of collected data are achieved. Multiple revising measures are adopted and computing precision of liquid weight is improved. Meanwhile a function of remote data transmission is achieved. The on-line computation device utilizing the liquid level method for computing the storage tank oil gas liquid chemical weight is applicable to computation of weight of liquid products in a fixed-roof oil tank, a floating-roof oil tank and a horizontal oil tank.
Description
technical field [0001] The invention relates to a metering device, and mainly relates to data collection and quality calculation of oil and gas liquefied chemical products. Background technique [0002] my country's petroleum and chemical companies adopt the transfer method of quality instead of volume for foreign oil trade. At present, there are two ways to measure the quality of oil and gas liquid chemicals that are invisible and intangible in storage tanks: manual measurement and automatic measurement. [0003] Manual measurement generally directly uses a ruler to measure the height of the oil in the storage tank or reads the relevant pressure gauges, and then calculates the volume and then the mass by checking the tank capacity table and other methods. This method has a large workload and poor real-time performance, and it is difficult to meet the requirements of customs and other regulatory agencies. [0004] At present, automatic metering generally adopts computer (P...
