Abstract
Objectives: In this paper, the aim is to show how to generate a gauging table with the continuous use of electrical, hydraulic and mechanical devices that aim to provide reliability, purity and industrial safety, by not directly manipulating the fuel and actions that may vary final product or induce accidents. In addition, by making a custom gauging table for the arbitrary conditions of the tank, the uncertainty about the quantity of the liquid is reduced and, therefore, it does not discriminate on the type, shape or physical characteristics of these, because the characteristic of the tank it is carried out in the place and under the operating conditions. Methods/Analysis: The model was developed in five stages, a saber: Analysis and specification, Design and construction, Evaluation, Modification and Testing. Findings: Through the implementation of this measure system reliability, safety, and decreased operating time thanks to a methodology of continuous high flow samples and offers. Improvements: The developed model can evolve to a system with greater automation, using level and flow sensors with the same or better resolution, which does not have its own interface for reading but can be added to the communication card and flow control, needing a single USB communication port for mobile phones, with the aim of developing the application on mobile phones. Keywords: Flow, Gauging, Storage Tank, Threats, Volumetric Filling
Highlights
In Latin America, several projects of gauging in the hydrocarbon sector have been carried out[1]
In Ecuador, the practice of tank gauging is mainly done through volumetric calibration of surface hydrocarbon storage tanks achieving the registration of height measurements, flow, and mathematical corrections respect to parameters that affect the reliability of the measurement such as temperature, inclination and coefficient of expansion of the liquid[2]
The third project implemented in the Leona brewery, designs and implements a gauging system for finished beer tanks controlled by means of an S7-200 PLC, flow and level sensors by ultrasound at the time of filling
Summary
In Latin America, several projects of gauging in the hydrocarbon sector have been carried out (process to determine the total capacity of the liquid storage tank, or the corresponding partial capacities at different heights)[1]. The second specific project for the implementation of a tank radio control robot, whose function is to scale vertically the tank and monitor the presence of the liquid to obtain the gauging table[4]. The third project implemented in the Leona brewery, designs and implements a gauging system for finished beer tanks controlled by means of an S7-200 PLC, flow and level sensors by ultrasound at the time of filling. This document presents the development of a continuous and high flow gauging system for storage tanks of surface and underground liquid fuels through the implementation of a hydraulic, electrical and electronic circuit that, through a program specialized in the process, controls and monitors the process through an interface that is manipulated by the operator. The hydraulic circuit fulfills the function of up to 100 gallons per minute that is accounted by two electronic circuits, in addition to detecting, communicating and controlling the flow
