Monitoring the Stability of Oxygen Flow Analyzer on Oxygen Station in the Hospital

Oxygen therapy besides having benefits also has certain dangers and side effects. For this reason, oxygen must be given at the proper dose by monitoring patient regularly adjusting flowmeter. The accuracy of flowmeter under standard conditions is guaranteed manufacturer. With time use precision may change flow in a hospital setting differ from original value. Thepurpose research to conduct further on analyzer which focuses discussing stability sensor against gold standard. Contribution study increase range flowrate measurement 15 liters per minute (LPM). This uses Arduino Mega while gas used legris sensor. results are displayed TFT LCD equipped with SD Card data storage. regulated using (GEA). Meanwhile comparison tools Analyzer 1 m3 cylinder. At testing stage, reading value module that appears compared resultsf tool LPM 6 times each point. conclusion these calibrator relative error still within allowable tolerance limit ±10%.
