Abstract

Liquified Petroleum Gas (LPG) is one of prepackaged product known as BDKT which is widely used by society. Legal Metrology is regulating prepackaged companies to fulfill for sale prepackaged conformity  in order to protect public interest through verifying the correctness of the prepackaged quantity. The application of the weighing method test has many shortcomings in terms of time, effort, and costs incurred. This research analyzes how to get the actual quantity of LPG products based on gas pressure using the ideal gas principle and makes a prototype by utilizing pressure sensor technology and microcontroller-based programming. The results of this research are a prototype to determine the mass of LPG gas in units of weight by using gas pressure measurements. The prototype is expected to be able to eliminate the shortcomings in testing the quantity of prepackaged using the weighing method test. The difference in pressure measurement of the prototype compared with a manometer is -0.05 atm. Measuring the mass value of LPG gas is done at 3 (three) different volume values reference with results of 0.249%, 0.430% and 0.618% for the nominal quantity value of 3 kg LPG.
