Nitrogen tank blanketing systems are used in various industries to prevent the degradation of a stored liquid or substance. Thermal mass flow meters are ideal for monitoring the inert gas consumption, improving safety, and saving on costs.
Many industries store liquids, gases, and even slurries in industrial storage tanks or vessels. Often, when the storage material comes in contact with oxygen, the substance oxidizes and degrades, lowering product quality or potentially creating a hazardous situation. Industries often use tank blanketing systems to remedy.
Tank blanketing systems fill the headspace of a tank storing the unstable liquid, gas or slurry, with an inert gas (such as nitrogen). The gas blankets the vessel’s content and prevents it from interacting with oxygen and breaking down. The majority of these systems do not measure the flow rate of the inert gas, and operators typically vary the flow rate as the contents are pumped from the tank, which can create a safety issue when over-pressurized. Additionally, extra nitrogen can be used, and be costly.
