Measurement Arrangements

Optimus™ is an externally mounted system and therefore is not

affected by adverse

conditions in the vessel (high pressures, temperatures, corrosive liquids). The system can
be used on numerous different shaped vessels.

Up to four PRI150 radiation detectors can be connected to a single Optimus™ control

module. This allows a measurement range between 0.24 to 17.28 metres in 0.24 metre
increments.
