Flow Measurement Effective, Economical Nitrogen Tank Blanketing
Process engineers in search of a flow measurement solution to support accurate, safe and economical nitrogen tank blanketing operations will find the ST Series Family of Flow Meters from Fluid Components International (FCI) provides a wide range of choices designed to accommodate various tank and line sizes.
Storage tank blanketing or padding by pumping inert nitrogen or other gases into the vapor space of a tank is designed to protect the contents. Depending on the specific type of product stored in the tank, blanketing can prevent contamination, toxic fume leaks, explosions or fires. The pressure of the blanketing gas pumped into the tank is slightly higher than atmospheric pressure, which is all that is necessary to achieve the desired results.
Accurately measuring the blanketing gas is important because adding too much gas is unsafe, wasteful and expensive. Most storage tanks are not generally designed for high pressure environments — so over-pressurization can be a dangerous issue. Installing an ST Series Flow Meter upstream from a tank’s regulator valve allows the monitoring and control of the nitrogen flow rate.
FCI’s mass flow meters are calibrated to specific gases such as nitrogen for superior accuracy in FCI’s NIST-approved Calibration Laboratory. Their thermal dispersion mass flow sensors and rugged packaging are suitable for a wide range of industrial process environments.
