Drinking water and grey/black water
Drinking water is an essential commodity on a ship. It is stored in separate dedicated tanks. Depending on the type and size of the ship, different amounts of fresh water are required for drinking, for personal hygiene as well as for cleaning. The amount of water stored in the tanks can be from 50 to 400 tons and depends largely on whether the ship has a desalinisation plant. Direct electrical measuring principles are mandatory for level measurement. Waste water, so-called grey/black water, is treated on large ships in on-board clarification plants, or stored in special grey/black water tanks to await final disposal.
Grey or black water measurement with VEGASON 61
Due to the large concentration of solids and the changing density of the tank contents, non-contact measurement with ultrasonic technology qualifies well for this application. The VEGASON 61 sensor with PVDF-encapsulated transducer is resistant against the corrosive gases in the tank and requires only a G 1½ threaded mounting boss as process fitting.
VEGABAR 54 in drinking water
Flanged directly onto the tank, VEGABAR 54 measures the level reliably and accurately. Materials approved for drinking water and a front-flush diaphragm form the basis of a flawlessly hygienic measurement. The rugged sapphire-ceramic diaphragm withstands chemical as well as mechanical cleaning. The external electronics can be mounted at an easily accessible place.
