DEMonitoring of cargo tanks
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. The charging and discharging procedures have to be especially carefully supervised and under control. Continuous level measurement and redundant monitoring of conveyor pumps with 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 overpressure or vacuum, during charging and discharging procedures or through fuctuations in external temperature.
Continuous level measurement with VEGAPULS 63
Radar measurement is not affected by product properties, temperature, pressure or superimposed gas. The PTFE antenna cover ensures optimum chemical resistance, even for applications in aggressive products. VEGAPULS 63 radar sensors deal with the changing conditions in the product tank safely and reliably.
Inert gas pressure measurement with VEGABAR 52
The VEGABAR 52 pressure transmitter is particularly suitable for monitoring the gas pressure in product tanks. Its ceramic-capacitive CERTEC measuring cell enables precise monitoring of the internal tank pressure to within a few millibars and also withstands pressure shocks caused by rough seas.
95% and 98% alarm detection with VEGASWING 63
Two VEGASWING 63 vibrating level switches are applied for 95% and 98% alarm detection. A rugged construction, hard-wearing tuning fork, reliable switching characteristics, and the ability to work with changing products, make VEGASWING 63 ideal for this application. Its test key makes fast and reliable on-site checking possible.
Multi-sensor flange
The small, compact construction of plics instruments allows a central installation of the radar, pressure and alarm sensors on one fange, together with a port for manual sounding. This brings enormous cost savings, in installation, setup and, as an additional plus, the complex correction tables for difering installation points on the tanks can be eliminated.
