Observator 100 years

Tank Level Systems

Monday 2 December 2013

The rich history of the Observator company is connected to the shipping and shipbuilding industry.

Observator supplies an array of instrumentation to the ships, one of these is a tankmonitoring system, which is based on the bubbler measurement principle. The own designed flowcontrollers, take care of a constant flow, through the bubbler tube, and the manometer gives the level information.

The system can be extended with an electrical output for each flowcontroler, which gives then a proportional 4/20 mA signal, to the tanklevel, which can be used in the ships automation system. Via the system the information can be seen throughout the vessel and all kind of handy functions can be added, e.g. overflow or low-level warning.

Example of such an installation is the DUKE II, with 15 tanks with local manometer indication and 4/20 mA output for each Tanklevel.

The instrumentation is all concentrated in one cabinet, the passive items are mounted outside the cabinet, and cannot fail due to flooding or bad conditions, like heat; moist; salt. We can supply a special sensor flange, for the measurement of drinking water.

Observator can also upgrade older systems, by supplying a new measurement cabinet for the existing bubbler system, in this way a simple upgrade can be performed.
