Tank gauge for LPG LNG plays an important role in the smooth functioning of the Petroleum Supply Chain. Some gaseous petroleum products like LNG and LPG (despite being part of the gas supply chain) are also measured by tank gauge for LPG LNG while in the liquid phase at the time of custody transfer or fiscal metering.
Industrial storage tanks usually contain large volumes of liquid product with significant fiscal value – the larger the tank larger is the financial impact of any incorrect operations. Tank gauge for LPG LNG is critically important for measuring liquids in large storage tanks. The ultimate objective is to accurately determine the value of volume and mass of the product in the tanks. The oil and gas industry generally uses static volumetric assessments of the tank content. However, mass measurements are also implemented in China.
Tank gauge for LPG LNG involves liquid level, temperature and pressure measurements. Since liquids undergo volume changes, depending on individual thermal expansion coefficient, there is an additional requirement for proper volume compensation during calculations of volumes at varying temperature conditions. Often, more significantly, for high vertical tanks and pressurised tanks, pressure measurement of the liquid head is important and included in calculating the pressure correction factor. This, in turn, provides an accurate assessment of the average observed density for converting volume to mass.
In addition, dimensional correction factors for variations in tank structural volume under changing operating parameters are applied to maximise liquid product quantity measurement accuracy. Tank gauge for LPG LNG scope varies and is dependent on 1) type of tank, 2) type of liquid, and 3) the purpose storage tank is used for.
