LPG and Propane is filled under pressure, stored and transported to the consumer. When the cylinder valve is opened reduction of pressure takes place and the liquid turns into gas. LPG and Propane is in gaseous form at ambient temperature and pressure, and LPG is almost twice as heavy as air. Hence, it always settles down to floor level in case of leakage. LPG and Propane is colorless and odorless. Therefore, a distinctive fuel odor is added before it is filled into cylinder to enable easy detection in case of leakage. The research concludes with the solution to address the problem in existing hydro carbon level measuring device inside the road tanker with an aim to improve the occupational health issue to loading and unloading operators, to reduce the revenue loss to the organization and also ratifies the field outcome of the hydrocarbon presence zone against the software results.
