Gas Leakage Detection System with Alarming System

Abstract

This system aims to present a design that can automatically detect, alarm, and control gas leakage using an exhaust fan to suck the gas away from the premises where there is leakage. This system detects the nature of gas using LEDs (red and green). The alarm gives a sound when gas leakage is detected, the exhaust fan sucks the gas away from the premise, and the Liquid Crystal Display (LCD) indicates the system performance at any distortion condition. The Arduino UNO is used as the main controller of the system, and the buzzer is used as a means of notification. One of the prophylactic means to stop accidents related to this gas leakage is to mount a gas leakage monitoring device in susceptible places. The system will detect the leakage of liquefied petroleum gas (LPG) using a gas sensor and use the buzzer to alarm the industries, companies, or people about the leakage. The system also consists of two indicators (LEDs). The Green LED used in this research indicates no gas detection, that is, there is no gas leakage in the environment, and the red LED will indicate that there is gas leakage detected. The device is intended for use in household safety where appliances and heaters that use natural gas or LPG may be a source of risk. The system can also be used for other applications in the industries or companies that depend on LPG and natural gas in their operations.

Analysis on Influence Factors of Differential Pressure Detection of Gas Leakage

“…The derivative of the fitting curve is obtained and substituted into the results of (16). The comparison diagram between the flow value finally obtained and the collected value of the smoothed flowmeter is shown in Figure 7(b).…”

“…In general, ultrasound testing method is difficult to be used in the running devices in practice. Similar to the ultrasonic method, it is used for gas detection in special occasions such as liquefied petroleum gas, which uses chemical methods to detect the concentration of a gas component in the environment to determine leakage [16]. However, this method is not universal, and the detection efficiency is generally low.…”

Optimal Dispatch of the Energy Demand in Electrical Distribution Grid with Reserve Scheduling

“…In this section, interval optimization is modelled for solving objective function subject to electrical price uncertainty [41]- [45]. In this approach, maximum and minimum bounds of the objective function are modelled based on an uncertain parameter [46]- [53].…”

Robotic Inspection Monitoring System for Pipelines

“…Pipelines are now the most widely used method of transport for gases and liquids (63)(64)(65). Therefore, ongoing pipeline monitoring is necessary to assure its safety and health [1].…”
