Storage tanks on board
The levels of storage tanks on board of chemical tankers must be continuously monitored because of strict safety and environmental requirements. Overfilling or product discharge on deck or into the sea could have devastating consequences for human life and the environment. Especially the charge and discharge procedures have to be carefully supervised and under control. Continuous level measurement and redundant monitoring of conveyor pumps by means of level switches are essential parts of the safety system.
The internal pressure of the tanks is monitored continuously to prevent damage to the tanks caused by gauge or low pressure during charge and discharge procedures or by external temperature fluctuations. All measured values and alarm signals are visualised both in the loading control room and on the bridge.
Continuous level measurement with VEGAPULS 63
Changing products, fluctuating temperature and different densities are a special challenge for the level meaurement in product tanks. The VEGAPULS 63 radar sensors are unaffected by temperature, pressure or gas stratification and deliver accurate measurement data right from the start. The measurement is insensitive to density fluctuations of the products because the sensor always measures the distance to the product surface. The PTFE coated antenna ensures optimum chemical resistance even for applications in aggressive products.
